AT least eight policemen have been killed in a bomb attack on a convoy in Egypt's Sinai Peninsula, officials say.

The bomb was reportedly detonated remotely as they travelled through the village of Wefaq, near the Gaza border.

Security forces have been carrying out an offensive in northern Sinai, killing and capturing dozens of suspected members of jihadist militant groups.

They have stepped up their attacks on soldiers and police since the overthrew of President Mohammed Morsi last year.
