A roadside bombing in Egypt's Sinai Peninsula killed two policemen on Monday, the interior ministry said.

The Islamic State group's self-styled Amaq news agency said a bomb planted by jihadists targeted a police mine clearing vehicle, but it was not clear whether it was referring to the same incident.

The interior ministry said a police lieutenant and a sergeant were killed when a roadside bomb tore through a convoy, also wounding two officers and a conscript.

Jihadists in the peninsula bordering Israel and the Palestinian Gaza Strip have killed hundreds of soldiers and policemen in attacks since the army toppled Islamist president Mohamed Morsi in 2013.
