Islamabad: At least 11 people were killed and 15 injured in a Shia-Sunni clash in Kohat Division's Kurram District on Monday.

The clashes between the two groups took place over the cutting of trees in disputed mountain forests, according to a reliable source.

"So far 11 people have been killed in cross-firing from both sides and 15 injured," said the source.

Heavy weapons were used and fighting has continued since yesterday. Police have been deployed and a jirga is also being held to restore peace.

Pakistan is facing rising sectarian violence, with armed Sunni groups linked to Al-Qaeda and the Tehreek-e-Taliban Pakistan often attacking gatherings of Shias, who make up some 20 per cent of the country's overwhelmingly Muslim population.
