Some 120 people were feared drowned after a boat packed with passengers and goods capsized on Ghana's Lake Volta, police in the West African country said on Monday. "There were 150 passengers on board but only 30 have been rescued. The rest are feared dead," police spokesman Kwesi Ofori said. He said the accident happened on Saturday and that a search party was still looking for survivors. Ofori said the boat was probably overloaded. He said it hit a stump as it travelled across the lake, which covers 8,500 square km (3,275 square miles), more than three times the size of Luxembourg. He said the bodies of three young children had been recovered from the accident site but gave no further details, according to a report of Reuters.
