A series of blasts in quick succession shook India's northeastern Assam state on Thursday, killing at least 65 people and wounding more than 300 others.

Many of Thursday's blasts were in crowded markets in the state. And many bombs were hidden in motorcycles or scooters.

Firefighters doused the smoldering remains of cars and motorcycles at one of the blast sites in Guwahati, a major city of Assam.

One of the bombs targeted a high security zone containing courts as well as offices and homes of senior police officials.
