Four Pakistani soldiers have been killed in two separate bomb explosions in the North Waziristan tribal district, local officials say.
Local administration officials told RFE/RL on November 4 that two soldiers were killed and another was wounded in a roadside bomb blast in the Razmak area.
The soldiers were on a routine patrol, the officials said.
Two more soldiers died in a second roadside bomb explosion in the town of Mir Ali.
Militants of Hizbul Ahrar, a splinter group from the Tehrik-e Taliban Pakistan (TTP), claimed responsibility for the attacks.
Pakistan launch a massive military operation in North Waziristan in 2014 to cleanse the region of Islamic militants.
