A car bomb blast late on Wednesday ripped through a luxury hotel’s parking area in the southwestern Pakistani city of Quetta, killing five people and wounding 11, officials said.

China’s ambassador to Pakistan was staying at the hotel, but was not there when the bomb exploded, said Pakistan’s interior minister, Sheikh Rashid Ahmad. Provincial home minister Ziaullah Lango said the envoy was fine.

“An explosion has rocked the parking area of the Serena Hotel,” police official Nasir Malik told Reuters, saying 11 people had been wounded. An official at a local civil hospital, Waseem Baig, said five people had died, and “several others are in critical condition”.

“A car that was full of explosives exploded in the hotel,” Ahmad told local ARY News TV.

The Pakistan Taliban claimed responsibility for the bombing. “It was a suicide attack in which our suicide bomber used his explosives-filled car in the hotel,” a spokesman for the militant group Tehreek-e-Taliban Pakistan (TTP) wrote in a text message to a Reuters reporter.

Chinese ambassador Nong Rong had earlier in the day met provincial chief minister Jam Kamal in the city, according to a tweet from the provincial government spokesman, Liaquat Shahwani.
