GHOTKI, Pakistan—An express train barreled into another that had derailed in Pakistan before dawn Monday, killing at least 51 people and setting off a desperate effort to search the crumpled cars for survivors and the dead, authorities said.
More than 100 other people were injured. Cries for help pierced the night as passengers climbed out of overturned or crushed rail cars. The pleas continued to echo throughout the day at the scene in the district of Ghotki, in the southern province of Sindh.
