Anxious relatives lined a river bank as rescuers searched the waters Thursday for up to 170 people missing from a ferry that capsized during a storm in central Bangladesh, killing at least 31 people, police and officials said. Strong currents and winds hit the overcrowded double-deck ferry ML Raipura on Tuesday as it carried about 250 passengers toward a terminal on the Padma River in central Manikganj district, 40 kilometers (25 miles) northwest of the capital, Dhaka. Rescuers plucked 29 bodies from the choppy river Thursday, raising the confirmed death toll to 31, said local police officer Abu Bakr Siddiqui. The bodies of a man and a child were found Tuesday and Wednesday. At least 50 people swam to shore.
