A roadside bomb in north-west Pakistan has killed 13 members of a wedding party and left about a dozen injured.
Children were among those hurt in the explosion
The incident took place in the Swat valley where the army has been battling pro-Taleban militants.
The wedding party was in the midst of celebrations, travelling in a convoy of three or four cars, when an explosion ripped through the vehicles.
An army spokesman said the bomb had been detonated by remote control. Women and children were among the casualties.
It was not clear whether the wedding party was the target or whether it was hit by mistake.
Roadside explosive devices are usually planted by Islamist militants battling the army.
The military began an offensive in the Swat valley several months ago against pro-Taleban insurgents who had infiltrated from strongholds near the Afghan border.
Since then it has claimed victory but observers say the situation remains unstable, with regular curfews, killings and thousands of troops still deployed in the area.
