Newly authenticated video shows protesters loyal to ousted Egyptian President Mohammed Morsi being gunned down by Egyptian forces on the streets of Cairo Wednesday.

Moments after moving toward the crowd, forces began firing on the protesters.

At one point, a loudspeaker announcement instructs the crowd to evacuate and promises safe passage, but moments later another vehicle approaches with the barrel of a weapon emerging from one of its gun ports.

The Associated Press authenticated the video based on landmarks and reporting from Wednesday’s crackdown.

The crackdown on pro-Morsi protesters began on Wednesday, with police using bulldozers and tear gas to push demonstrators out of two encampments. Police fired on protesters, prompting clashes that have lasted for three days now.

Egypt’s government put the country under a month-long state of emergency and put a curfew in place in Cairo and in 10 other provinces.

On Thursday, interim Prime Minister Hazem el-Beblawi authorized police to use deadly force to protect themselves and government buildings.

As of Friday afternoon, 37 people had been killed in the day’s clashes. That’s in addition to the Ministry of Health’s official death toll, released Thursday, of 638 people. That number includes the deaths of 43 police officers.

There have been questions raised about the official death toll numbers, released by the government.

Morsi supporters say the number is much higher and bodies taken to mosques have not been taken into account.
