What did officials say about the crash and rescue efforts?
"A passenger bus travelling from Quetta to Peshawar plunged into a deep ravine in the mountainous Dana Sar area ... Forty people have been confirmed dead and 11 others injured," said Sanaullah Sherani, the head of the emergency center in Zhob district near where the incident took place.
Sherani said that the bus fell 70 to 80 feet (roughly 21 to 24 meters) off the ravine.
"As the accident occurred in a rugged mountainous area, rescue teams faced significant difficulties during the initial phase of the operation," he said.
The bus lost control, veered off the road and fell into the ravine, according to Shahid Rind, a spokesperson for the Balochistan government.
Dana Sar is near the border of Balochistan and Khyber Pakhtunkhwa provinces.
Rind said the bus was overcrowded in part because it had stopped to pick up passengers from another bus that had broken down.

Rescue workers used cutters and machines to retrieve victims from the wreck of the vehicle before transporting the injured to nearby hospitals.
Some of those injured were reported to be in critical condition.
Pakistan President Asif Ali Zardari and Balochistan Chief Minister Sarfraz Bugti have expressed condolences to the victims' families.
