Clashes near the U.S. Embassy in central Cairo between police and Egyptians incensed over a film denigrating the Prophet Mohammad entered their fourth day early on Saturday, Sept 15, leaving one protester dead and dozens more injured, Reuters reported.

The clashes moved to a main road on the banks of the Nile after authorities closed the street leading to the embassy. The protesters, many of whom are intent upon breaking into the embassy, now are seeking alternative routes to the site.

A 35-year-old protester died from bird shot wounds late on Friday, three days after protesters climbed the embassy's walls and tore down the American flag.

"God is Greatest" and "There is no God but God," one group near the front of the clashes chanted as some threw stones on Friday on a street leading from Tahrir Square to the embassy nearby, as police in riot gear fired off rounds of tear gas.

Hundreds of protesters gathered in streets near the mission late into the night, pelting police with stones and petrol bombs as they were pushed back from the embassy perimeter.

The state news agency said 27 people were injured on Friday. Based on figures it announced on other days, that suggested more than 250 people have been injured during clashes this week after Tuesday's breach of the embassy.
