CAIRO — An explosion has hit a bridge near an upscale neighborhood in central Cairo, killing at least one person. An Associated Press reporter saw a corpse on the bridge, which connects Cairo's sister city of Giza to its upscale Zamalek neighborhood. A police officer at the scene said one person was killed in Sunday's blast. Explosions sometimes hit civilian areas. Last week, a militant group known as Ajnad Misr, or “Egypt's soldiers,” claimed responsibility for a bombing in front of Cairo University that wounded eight people, including four police officers. Another bomb exploded Saturday, causing no casualties. — AP
