Violence continued to rock strife-torn North Cachar Hill district of Assam with 14 houses in a Dimasa tribal village set ablaze on Wednesday.

The Lok Sabha was adjourned for the second time on Monday as Assam MP S K Bwiswmuthiary staged a sit-in protest over the ethnic violence in his state that has claimed 49 lives earlier this month.

As the death toll in Assam's ethnic violence mounted to 52, the Union Home Ministry has sent an advisory to the Tarun Gogoi-led Congress government asking it to take all necessary steps to protect lives and property of innocent people.

The situation continued to be volatile in Udalguri and Darrang districts with one more person killed on Tuesday, raising the death toll to 41. With indefinite curfew and shoot-at-sight continuing in the two districts, the army staged flag marches to prevent recurrence of further trouble.

With ethnic violence spreading to new areas in Assam, the Centre on Monday despatched 1,400 para-military force personnel to the strife-torn state where bloody clashes between Bodo tribes and immigrant Muslims claimed at least 40 lives.
