Another bombing in Cairo

Shit:

CAIRO, Egypt - A bomb was thrown from a bridge in Cairo to the street below, killing an Arab man and injuring four foreigners, police said.

Remains of a body, covered with newspapers, were seen beneath the bridge a few minutes after the 3:15 p.m. (7:15 a.m. ET) explosion was heard through downtown Cairo. The blast happened on a road adjacent to a public bus station down the street from the Egyptian Museum.

Reuters reports it might be a suicide bomber, but with these things the first reports are always very hazy.
