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

Axar.az reports citing foreign media that 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 four people had died, and “several others are in critical condition.”
