Several gunmen have stormed a five-star hotel in the restive Pakistani province of Balochistan, officials say.
Firing is reportedly continuing around the Pearl Continental Hotel in the port city of Gwadar, the focal point of a multi-billion-dollar Chinese project.
Officials say most guests at the hotel, popular among foreign tourists and business people, have been evacuated.
Balochistan, home to a long-running insurgency, is Pakistan’s poorest and least developed province.
Militant groups, including Baloch separatists, oppose the Chinese investment, saying they are of little benefit to local people, the BBC’s Jill McGivering says.
At least three armed men stormed the hotel at around 16:50 local time (11:50 GMT).
It is unclear how many people were inside the hotel but officials said the majority of guests had been evacuated.
Several militant groups operate in Balochistan, including the Pakistani Taliban, the separatist Balochistan Liberation Army and the Sunni Muslim extremist group Lashkar-e-Jhangvi.
