A roadside bomb on Wednesday killed three soldiers in Pakistan’s troubled northwest.

A roadside bomb on Wednesday killed three soldiers in Pakistan's troubled northwest, officials said.

The remote-controlled device hit a convoy of the paramilitary Frontier Corps as it was moving from the town of Hangu to Kurram district, one of seven tribal areas along the Afghan border where militants have strongholds.

A security official in Peshawar, the main city in the northwest, told AFP the blast killed three soldiers and wounded 11.

Another security official said the death toll may increase as some of the injured were in a critical condition.

The Pakistani Taliban announced a month-long ceasefire on Saturday in a bid to restart stalled peace talks with the government.

The military halted air strikes on suspected militant hideouts in response.

But a major attack on a court complex in Islamabad on Monday that killed 11 has cast doubt on the ceasefire, although the Taliban denied responsibility for the attack.

Taliban and Al-Qaeda-linked militants frequently launch attacks across northwest Pakistan and the lawless tribal belt, which Washington has branded the most dangerous place in the world.
