Indian police say an explosion at a Hare Krishna temple in the northeastern state of Manipur has killed five people and wounded at least 40 others, including eight foreigners.
Authorities say some victims of the bomb attack Wednesday evening are in critical condition, and the death toll could rise. The blast went off at a temple of the International Society of Krishna Consciousness, or ISKCON, in a heavily guarded security zone of Imphal, the Manipur state capital.
A large crowd was at the scene of the explosion, taking part in holiday celebrations marking the traditional birthday of the Hindu god Krishna.
Authorities say there is no definite motive for the attack, which they are describing as a powerful bomb blast. Other accounts report the explosion came from a hand grenade thrown by unidentified attackers, who then escaped in the confusion.
Indian authorities say one of those killed was a child. The wounded include at least three Americans and a French national.
No one has claimed responsibility for the attack, but authorities said they believe a local group was responsible. At least 10 rebel guerrilla groups - some seeking autonomy, others campaigning for expanded rights for ethnic minorities - operate in Manipur state, part of India's turbulent northeast. Most residents of the area are Hindu.
