Students bodies, political parties and a rebel group today called back-to-back bandhs for three days, starting from tomorrow, in Meghalaya to protest a police firing at disputed Langpih village along Assam-Meghalaya border, which left four people dead.

Influential Khasi Students' Union along with other such bodies have called a 24-hour bandh from 5:00 am tomorrow.

United Democratic Party (UDP), a constituent of the Congress-led ruling Meghalaya United Alliance (MUA) has called for a 12-hour bandh from 5:00 am on Wednesday.

The proscribed Hynniewtrep National Liberation Council has called for a 12-hour bandh from 5:00 am on Thursday.

The Meghalaya government, meanwhile, has decided to take up the killing of four villagers in Langpih by Assam Police with the Centre.

"Chief minister Mukul Sangma would soon meet Prime Minister Manmohan Singh and union home minister P Chidambaram to demand Centre's intervention and deployment of paramilitary forces in Langpih," state home minister H D R Lyngdoh said here yesterday.

"The situation is still tense, but the state government is doing its best to instill confidence in the minds of the villagers by deploying one company of Meghalaya Police," he said.

NCP leader P A Sangma demanded legal action against the Assam Police.

"Meghalaya government must register a case against the Assam Police and initiate legal action," he said.

Meghalaya chief minister in a statement last night had said, "Political parties are trying to politicise the issue whereas they should react responsibly in this hour of crisis."

On May 14, four persons were killed and over 20 injured in a clash between two communities and subsequent police firing at Langpih, claimed by both the states citing contradictory documents from history and land records.
