A police official told media that a collision between 2 passenger express trains in southern Pakistan claimed at least 30 lives on Monday, and the death toll was likely to increase as rescue teams were still trying to access several mangled coaches.

In a statement, a spokesperson for Pakistan Railways said the mishap took place in the Ghotki district of the southern Sindh province after the coaches of one train, the Millat Express, derailed and fell across the opposite track, where they were hit by another train, the Sir Syed Express.

Umar Tufail, a senior district police official, told local television channel Geo News that at least 30 dead had been taken to nearby hospitals, and rescuers were still trying to access a coach where some 25 people were believed to be trapped.

“Shocked by the horrific train accident at Ghotki early this morning leaving 30 passengers dead,” Prime Minister Imran Khan tweeted, noting that he was ordering a comprehensive probe into railway safety issue.
