A bomb exploded near a police checkpoint on bridge in an affluent Cairo neighbourhood on Sunday, killing an officer, Egyptian police officials said. The bomb had been placed next to the checkpoint on a side of the May 15 bridge located in the neighbourhood of Zamalek, the officials said.
Two people were wounded in the blast, which tore the victim's body to pieces, a health ministry official said. An AFP correspondent said there was a pool of blood next to the checkpoint.
Militants have repeatedly set off bombs in Cairo targeting police checkpoints and vehicles. The more sophisticated attacks have been claimed by jihadist group Ajnad Misr, which says they were carried out in retaliation for the deaths of hundreds of Islamist protesters in the past two years.
After the military overthrew Islamist president Mohamed Morsi in 2013, authorities unleashed an extensive crackdown on his supporters that left hundreds dead and thousands in prison.
In the Sinai peninsula, Islamic State group affiliated jihadists have killed scores of soldiers and policemen, including at least 15 troops in coordinated attacks last week.
