A bomb exploded outside a police training center in northeast India on Tuesday, killing at least 14 people and wounding 20 more, police said.
The bomb was apparently planted on a motorcycle and placed outside the center in the city of Imphal, said city Police Chief Radheshyana, who goes by just one name.
The wounded have been taken to local hospitals and several were in a critical condition, he said.
The center is used by police commandos, he said.
Imphal is the capital of India's Manipur state, which borders Myanmar.
Dozens of militant separatist groups are active in India's northeast, an isolated region wedged between Bangladesh, Bhutan, China and Myanmar with only a thin corridor connecting it to the rest of India.
The militants say the central government in New Delhi, 1,000 miles to the west, exploits the northeast's natural resources while doing little for the region's indigenous peoples, most of whom are ethnically closer to Burma and China than to the rest of India.
More than 10,000 people have died in separatist violence over the past decade in the region.
