Storms Sink Ships Rescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing or feared dead. The two ferries sank in different rivers near the capital city of Dhaka as strong winds and rain hit the South Asian country. The government has since banned all ferries and other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made for just 300. Police said the second ferry carried about 100 passengers. "The number of deaths is certain to rise, "said an official in charge of the rescue work, "No one really knows how many people were on board the ferry or how many of them survived.
