Deputy Commissioner of Diamir Arif Ahmed said in a video statement that some unknown gunmen opened fire at a passenger bus in the Hudar Pari point of the Chilas area in Diamir, leaving eight people dead on the spot, Xinhua reported.
Two soldiers are also among the killed, who were going to their hometowns on vacations, said the official.
Police, security forces and rescue teams rushed to the site and shifted the bodies and injured to a nearby hospital.
The medics feared that the death toll might further rise as some of the injured were in critical condition, added the official.
The bus was heading towards the eastern Rawalpindi city adjacent to the capital Islamabad from the Ghizer district of Gilgit-Baltistan when it came under the attack.
Following the attack, the driver of the bus lost control and hit the vehicle into a truck on the road which ignited fire and burnt the truck. The driver of the truck is also among the deceased people, said the reports.
No group has claimed responsibility for the attack yet.
