India ? An explosion today derailed an overnight passenger train that was then hit by a cargo train in eastern India, killing at least 65 people and injuring more than 200, officials said.

The passenger train was traveling from Calcutta to the city of Kurla when 13 cars derailed in a rural part of West Bengal state, about 90 miles south of Calcutta. A cargo train then slammed into three of the cars from the other direction, Railway Minister Mamata Banerjee said.

West Bengal state Home Secretary Samar Ghosh said 65 people were confirmed dead and more than 200 people were injured.

The train derailed as it traveled through a rebel stronghold, officials said.
