Officials in northeast India say at least 44 people have died and more than 100 were wounded in a wave of bomb and shooting attacks in the states of Assam and Nagaland.

Authorities in Nagaland say two bomb blasts minutes apart killed at least 26 people and wounded at least 86 others in Dimapur, the state's commercial hub.

Police say no one has claimed responsibility for the attacks in Nagaland, home to a long-running separatist conflict.

Authorities in the neighboring state of Assam say 18 people died in a string of attacks there. They say that in the deadliest attack, 11 people were killed and at least 12 others injured when unidentified gunmen sprayed gunfire at a market place in the village of Makri Jhora.
