[Dawn] A roadside bomb exploded alongside a military convoy, killing three soldiers and wounding another four in the North Waziristan tribal region on Saturday, security officials said. Suspected Taliban militants detonated the remote-controlled device as the convoy left Razmak military base, one official told AFP.
The convoy was moving towards a military post in the area, another security official said. One vehicle hit by the bomb was destroyed, he added.
Razmak is the main military base in North Waziristan, which is part of the country's lawless tribal region on the Afghan border where Taliban and Al-Qaeda-linked militants have carved out sanctuaries.
Troops are preparing to launch a major ground offensive against militant hideouts in South Waziristan, where supporters of slain Pakistani Taliban chief Baitullah Mehsud are entrenched.
A bomb attack killed one soldier and wounded two others in Jandola town of South Waziristan, a security official said.
The improvised-explosive device was planted on the road and exploded near a military vehicle, causing the casualties, he said.
