“A suicide bomber rammed an explosive-laden vehicle into a military convoy,” said a local government official in North Waziristan district of Khyber Pakhtunkhwa province, who asked not to be named because he was not authorised to speak to the media.
He said 16 soldiers were killed, up from the earlier reported toll of 13.
The attack in north-western Pakistan also left 29 people injured, including 10 army personnel and 19 civilians.
