COLOMBO, Sri Lanka - A bomb ripped through a compartment of a packed Sri Lankan passenger train during evening rush hour Monday, killing seven people and wounding 62 others.

Military spokesman Brig. Udaya Nanayakkara blamed Tamil separatists for the bombing, which occurred near Colombo, the capital.

Rebel spokesman Rasiah Ilanthirayan did not respond to calls seeking comment, but the rebels routinely deny such attacks.

Television footage showed the blast ripped off part of the train compartment's roof and shattered its window.

A blast blamed on the rebels at a Colombo bus station last month killed 26 people.

The Tamil Tigers rebel group has fought since 1983 to create an independent homeland for ethnic minority Tamils. More than 70,000 people have died in the fighting.
