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.

Attacks mainly targeting Egyptian security forces have spiked since the 2013 military overthrow of Islamist President Mohammed Morsi following massive protests against his divisive rule.

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.
