A passenger train in Pakistan smashed into derailed carriages from another train on Monday, killing at least 36 people, government officials said.
The death toll was likely to rise as rescuers struggled to reach people trapped in several mangled compartments strewn across the tracks in the southern province of Sindh.
A Pakistan Railways spokesman said at least 33 bodies had been taken to hospitals, among them two railway officials. More than 100 people were injured, he told Reuters.
Police officer Umar Tufail said the toll rose to 36, and that his men could see four more bodies stuck in the wreckage.
"We have not been able to take them out so far, but an operation is underway for that," he told reporters at the site. "We have saved three more people; they are injured," he added.
The Pakistan Railways spokesman said several carriages of the first train fell across the adjacent track after the derailment in the Ghotki district.
The second train, coming from the other direction, then smashed into them, he added.
"The driver tried to apply emergency brakes but the locomotive hit the infringing coaches," Pakistan Railways said in an initial report.
"The track has got issues on several points, the coaches are old, some as old as 40 years," railway official Khalid Latif told Geo News TV.
"I've told high-ups several times 'please do something about it'," he said.
Prime Minister Imran Khan said on Twitter he was shocked by the "horrific" accident and was ordering a comprehensive investigation into railway safety.
