A bomb struck a bus carrying Egyptian policemen Monday, killing two and wounding 24, police said, the latest attack against security forces who are being targeted by the Takfiri group, ISIL (so-called Islamic State in Iraq and Levant).

The attack occurred in the Nile Delta province of Baheira, 260 kilometers (162 miles) north of Cairo, while the policemen were travelling to work in a civilian bus.

"Two policemen were killed and 24 others were wounded, including two seriously," said health ministry spokesman Hossam Abdel Ghaffar.

A local health official earlier told AFP that one policeman had died in the blast.

Takfiris from Egypt's ISIL affiliate have launched regular attacks against security forces since the army's ouster of president Mohammad Mursi in 2013.

Most of their attacks are in the Sinai Peninsula, but deadly bombings have also been carried out in other cities including Cairo.

The extremists say their attacks are in retaliation for a police crackdown targeting Mursi supporters that has left hundreds dead and thousands jailed.
