'Bomb blast' near Afghan mosque

A bomb blast near a mosque in the southern Afghan province of Helmand has killed at least two policemen and injured several others, officials say.

A landmine detonated under the police vehicle in Gereshk district, officials said. Some reports put the number of casualties higher.

Hundreds were at the mosque to mark the start of the Eid al-Fitr festival.

Violence has soared this year with more than 3,000 people killed as Afghan and foreign forces battle Taleban fighters.

Earlier this week two people were killed and at least 10 injured after gunmen opened fire in a mosque in Wardak province bordering Kabul.
