At least 26 people have been killed and dozens were battling for their lives after six units of the famed marble mines in Pakistan’s Ziarat Ghar mountain collapsed, causing large boulders to fall on them, according to media reports on Tuesday.

The mines collapsed on Monday night, instantly killing 12 miners, the Geo News reported. The death toll rose after 10 more succumbed to injuries at the District Mohmand Hospital.

Majority of the deceased include labourers and few others who had gathered at the foothill in Khyber Pakhtunkhwa’s Safi town near the Afghanistan border, about 85 km from provincial capital Peshawar.

Mohmand District Police Officer Mohmand Tariq Habib told Geo News that people are still buried under the rubble
