NEW DELHI, Sept. 27 (Xinhua) -- At least three people have been killed and seven others injured after two groups opened fire at each other following heated arguments in the western Indian state of Rajasthan Thursday, police said.

The incident took place at Bhilgawan village in the state's Dholpur district.

"Both groups clashed and fired at each other after heated arguments between them this morning, in which three people died on the spot while seven sustained injuries," local police chief Dusht Daman Singh told the media.

The injured have been hospitalized, another police official said, adding that there has been heavy deployment of force in the village.

No one has been arrested yet, the official said. "But a case has also been registered against members of both the groups though it seemed to be a case of personal rivalry. All the accused will soon be nabbed," he added.
