At least 14 Pakistani soldiers were killed and more than 20 others injured on Sunday when a security forces convoy was targeted by a roadside bomb in the country's lawless North Waziristan tribal region.
The incident occurred near Miranshah, the main town of North Waziristan tribal agency, security officials were quoted as saying by TV news channels.
They said 14 soldiers were killed and over 20 injured in the attack.
No further details were immediately available.
The attack came just a day after Tehrik-e-Taliban Pakistan chief Hakimullah Mehsud reportedly directed his militants not to target Pakistani troops in North Waziristan.
