One of the Taliban officials said the drone fired a missile at a hujra, or guesthouse on the compound of Maulvi Faqir Mohammad, a senior leader of the TTP movement.

"It was around 3:30 when a drone suddenly appeared in the sky. We got worried and advised Maulvi Faqir to go to a safe place but he refused and argued it was not possible to hide in the day time," said the official, who spoke on condition of anonymity.

Around half an hour later, when Faqir Mohammad left his own house to visit the guesthouse, the missile struck.

"He was about 3 metres away from the hujra room when the drone fired a missile and hit the same room. Luckily the missile didn’t explode and he and other people around him remained safe," he said.

Faqir Mohammad is a former deputy leader of the TTP who spent eight years in Afghanistan's Bagram prison before being released by the Afghan Taliban following their shock overthrow of the Western-backed government in Kabul on Aug. 15.
