AFP, MULTAN: At least four people were killed and more than 100 injured when two trains collided in central Pakistan early Thursday, officials said. The accident occurred when the Karachi-bound “Awam Express” passenger train rammed into a goods train that had stopped after running over a man near the city of Multan. Rescue workers used metal-cutting equipment to try to reach injured passengers still trapped in the mangled wreckage, according to an AFP reporter at the scene. Mohammad Javed, 35, a shopkeeper who lives near the site of the crash said he had been woken up by “a huge blast”. “I thought that some bomb had exploded,” he told AFP.
