A Pakistan military helicopter taking diplomats to inspect development projects crashed on Friday killing seven people, including the ambassadors of Norway and the Philippines and the wives of the Malaysian and Indonesian ambassadors, the army said.
Prime Minister Nawaz Sharif was traveling to the mountainous northern region of Gilgit on a separate aircraft to launch two projects when the accident happened. He returned to Islamabad, his office said.
As well as Norwegian Ambassador Leif Larsen, Philippine Ambassador Domingo Lucenario and the wives of the ambassadors of Malaysia and Indonesia, the two pilots and a crew member were killed, military spokesman Asim Bajwa said in Twitter posts.
He said initial information indicated the cause was a technical fault.
He said the ambassadors of Poland and the Netherlands were among the injured. The ambassadors of Canada, South Africa, Lebanon and Romania were also on board, according to a flight list obtained by Reuters. The Romanian Foreign Ministry said its ambassador was alive and uninjured.
An official in Gilgit said nine people had been killed.
"The bodies are so badly torched that they can't be identified," said Sibtain Ahmed, the home secretary of Gilgit-Baltistan.
The Foreign Office said 17 people were on board the MI-17, one of four helicopters taking people to the projects, when it crashed into a school Gilgit and caught fire. Media said there were 11 foreigners and six Pakistanis.
Farmer Shakil Ahmed saw the helicopter crash into the roof of the Naltar Snow School from his house about 100 meters away.
"The helicopter came very close to the helipad, maybe 250 meters in the air, just above the school," Ahmed told Reuters.
"It hovered there for a while and then tried to turn when it crashed. Thankfully there were no kids in the school because it was an off-day for security reasons. The helicopter caught fire and was on fire for over an hour."
Pakistani Taliban militants claimed they had shot down the helicopter with a shoulder-launched missile adding they had been hoping to shoot down Sharif's aircraft.
"Nawaz Sharif and his allies are our prime targets," Taliban spokesman Muhammad Khurasani said in an emailed statement.
Gilgit is not a militant stronghold and the Taliban often claim responsibility for incidents that they had nothing to do with.
