London Ambulance Service said it was treating a number of people at the scene.
The Metropolitan Police said it was awaiting updates on the condition of those injured.
A large police cordon stretches from Streatham Hill station and there is a heavy police presence; helicopters are overhead.
Gulled Bulhan, a 19-year-old student from Streatham, saw the shooting take place in front of a Boots pharmacy.
"I was crossing the road when I saw a man with a machete and silver canisters on his chest being chased by what I assume was an undercover police officer," he told the PA news agency.
"The man was then shot. I heard three gun shots."
Eyewitness Daniel Gough said he was out for a run when he heard the shots and everyone ran.
"There was panic, people were yelling," he said. "A young girl running alongside me kept asking 'Is this what I'm meant to do' - she was very distressed.
"I saw a policeman and he yelled, telling everyone to get back. His gun was pointing in the direction of a man on the floor.
"Suddenly, more police appeared. There were [officers] everywhere".
Mayor of London Sadiq Khan thanked emergency services for their "swift and courageous response", saying: "They truly are the best of us."
"Terrorists seek to divide us and to destroy our way of life - here in London we will never let them succeed."
Streatham's Labour MP Bell Ribeiro-Addy said her thoughts were with those injured, their families and those who witnessed the attack.
BBC journalist Steffan Powell, in Streatham, described how the incident unfolded at the bottom of his road.
"There were armed police everywhere, they have been telling residents to stay inside," he told BBC News.

Philippines health officials announced Sunday that a 44-year-old Chinese man had died the day before from coronavirus after flying into the country from Wuhan, the Chinese city of 11 million at the center of the outbreak.
There are more than 14,300 confirmed cases around the world, and 305 people have died. All but one of the deaths have been in mainland China.
Within China, almost 60 million people remain on effective lockdown as the country battles to contain the virus amid reports its health system is on its knees, running out of beds and supplies.
International response
There are now more than 160 confirmed cases in 26 countries or territories outside of mainland China. And as the virus continues to spread around the world, governments are stepping up their responses.
The United States, Australia and New Zealand have all announced that they will not allow foreign nationals who have traveled from or transited through China to enter. All three countries will continue to allow citizens who have visited China to enter, although they will need to be quarantined.
Some governments have also raised their travel advisory warnings. The US, for instance, has labeled China a "do not travel" destination -- the highest possible warning.
A number of countries have evacuated their citizens from Wuhan. The US evacuated 195 Americans, who are under a 14-day quarantine on an air force base in California.
US Defense Secretary Mark Esper has also approved a request to provide military housing for up to 1,000 people who may need to be quarantined after arriving in the US from overseas travel, the Pentagon said in a statement.
Fears over the pandemic have rattled global stock markets and forced both US and global carriers to amend flight schedules as demand for China travel declines.
Major airlines -- including British Airways and Australia's Qantas -- have announced they will no longer fly to mainland China. Delta said it will suspend flights between the US and China starting on Sunday until at least April 30, according to a press release.
Chinese response
In mainland China, tens of millions of people remain under effective quarantine after the government imposed travel restrictions on a number of cities in Hubei province. Wuhan -- where the outbreak was first reported -- is the capital of Hubei province.
Although the outbreak has spread to every province and region of China, the outbreak remains worst in Hubei, where more than 7,100 have been diagnosed with coronavirus and 249 people have died.
A total of 57 million people across 15 cities in Hubei are on some form of lockdown. Huanggang -- a city of 7.5 million in Hubei province -- is only allowing one representative from each household to leave their home every other day to go out for grocery shopping in order to minimize the flow of people in the city.
The unprecedented decision to shut down entire cities comes as the country faces a shortage of medical supplies. Chinese Premier Li Keqiang has even asked the European Union to help China procure medical supplies, according to a Chinese government statement.
Patients and medical staff have also told CNN of delays in testing for the virus, raising concerns that the outbreak in China may be worse than is reported.
CNN's Yong Xiong and Steven Jiang in Beijing; and Carly Walsh in Hong Kong contributed reporting.

The U.S. plan would grant the Palestinians limited self-rule in parts of the occupied West Bank, while allowing Israel to annex all its settlements there and keep nearly all of east Jerusalem.
The summit of Arab foreign ministers in Egypt’s capital Cairo was requested by the Palestinians, who responded angrily to the American proposal.
Abbas said he told Israel and the U.S. that “there will be no relations with them, including the security ties” following the deal that Palestinians say heavily favors Israel.
The Western-backed Palestinian leadership has been under mounting pressure from ordinary Palestinians and its rivals in the Islamic militant group Hamas to cut off security ties with Israel and the U.S. or even dismantle the increasingly unpopular Palestinian Authority.

That would leave Israel responsible for the complicated and expensive task of providing basic services to hundreds of thousands of Palestinians in the West Bank.
Abbas could also cut off agreements with U.S. intelligence agencies to combat extremism.
There was no immediate comment from U.S. or Israeli officials on Abbas’ statement.

The Palestinian leader said he refused to take U.S. President Donald Trump’s phone calls and messages “because I know that he would use that to say he consulted us.”
“I will never accept this solution,” Abbas said. “I will not have it recorded in my history that I have sold Jerusalem.”
He said the Palestinians remain committed to ending the Israeli occupation and establishing a state with its capital in east Jerusalem.
Abbas received a long applause from the Arab foreign ministers in attendance after his speech.
Abbas said the Palestinians wouldn’t accept the U.S. as a sole mediator in any negotiations with Israel. He said they would go to the United Nations Security Council and other world and regional organizations to “explain our position.”
The Arab League’s head, Ahmed Aboul-Gheit, said the proposal revealed a “sharp turn” in the long-standing U.S. foreign policy regarding the Israeli-Palestinian conflict.
“This turn does not help achieve peace and a just solution,” he declared.
Aboul-Gheit said that the Palestinians reject the proposal. He called for the two sides, the Israelis and the Palestinians, to negotiate to reach a “satisfactory solution for both of them.”
President Trump unveiled the long-awaited proposal Tuesday in Washington. It would allow Israel to annex all its West Bank settlements — which the Palestinians and most of the international community view as illegal — as well as the Jordan Valley, which accounts for roughly a fourth of the West Bank.
In return, the Palestinians would be granted statehood in Gaza, scattered chunks of the West Bank and some neighborhoods on the outskirts of Jerusalem, all linked together by a new network of roads, bridges and tunnels. Israel would control the state’s borders and airspace and maintain overall security authority. Critics of the plan say this would rob Palestinian statehood of any meaning.
The plan would abolish the right of return for Palestinian refugees displaced by the 1948 war and their descendants, a key Palestinian demand. The entire agreement would be contingent on Gaza’s Hamas rulers and other armed groups disarming, something they have always adamantly rejected.

Ambassadors from the United Arab Emirates, Bahrain and Oman attended the Tuesday unveiling in Washington, in a tacit sign of support for the U.S. initiative.
Saudi Arabia and Egypt, Arab states that are close U.S. allies, said they appreciated President Trump’s efforts and called for renewed negotiations without commenting on the plan’s content.
Egypt urged in a statement Israelis and Palestinians to “carefully study” the plan.
Jordan, meanwhile, warned against any Israeli “annexation of Palestinian lands” and reaffirmed its commitment to the creation of a Palestinian state along the 1967 lines, which would include all the West Bank and Israeli-annexed east Jerusalem.
Jordan and Egypt are the only two Arab countries that have peace treaties with Israel.
