An attack on a luxury hotel in the southwestern city of Gwadar was a bid to “sabotage prosperity”, Pakistani prime minister Imran Khan said Sunday, as police confirmed all the attackers had been killed.

At least one person was shot dead Saturday after gunmen stormed a luxury hotel in the southwestern Pakistani city of Gwadar, the centrepiece of a multi-billion dollar Chinese infrastructure project.

“Such attempts especially in Balochistan are an effort to sabotage our economic projects and prosperity. We shall not allow these agendas to succeed,” Khan said in a statement issued by his office.

The Pearl Continental, part of Pakistan’s largest five-star hotel chain, is the only luxury hotel in Gwadar, frequented by foreign and Pakistani business delegations as well as diplomats.

It sits isolated on a ridge overlooking the Arabian Sea port city that was formerly a small fishing village, but now touted by officials as “the next Dubai” thanks to the multi-billion dollar China-Pakistan Economic Corridor.

His account was confirmed by a security source in Islamabad. The military had said on Saturday that there were three gunmen.Mohammad Aslam, a police official in Gwadar, told AFP Saturday that only staff were present in the building at the time of the attack.

The BLA is one of a myriad of insurgent groups fighting in tightly-guarded Balochistan province, which has been rocked by separatist, Islamist and sectarian violence for years.

Part of China’s Belt and Road initiative, CPEC seeks to connect the western Chinese province of Xinjiang with Gwadar, with the development of the port as the plan’s flagship project.

Gwadar will provide China with safer and more direct access to the oil-rich Middle East than the waterway trade route it currently uses through the narrow Malacca Straits.

But it has also drawn its share of attacks particularly from separatists who have long complained that residents of Pakistan’s poorest and largest province do not receive a fair share of profits from its resources.

The BLA has targeted Chinese workers in Pakistan multiple times, including during a brazen daylight attack on the Chinese consulate in Karachi which killed four people in November last year.
