The Manipur state government has extended its internet services ban until 10 June (Saturday) to prevent misinformation in violence-hit regions. The ban was imposed on 3 May.
The move came after fresh violence was reported in the state on Sunday, when three were reportedly killed and four injured.
It was also reported that 200 houses were burnt on Friday night, including that of Congress lawmaker Kangujam Ranjit at Serou in the state's Kakching district.
Last week, federal Home Minister Amit Shah visited the state's troubled areas and urged communities to surrender their weapons, stop blocking roads, abandon violence.
Shah also announced that he would form a three-member commission headed by Ajay Lamba, a former Chief Justice of the Gauhati High Court, who will investigate the ethnic violence and submit his report within six months.
According to local media, 10,000 Indian army and Assam Rifles personnel have been deployed in the state. In addition to the internet service ban, the state is also imposing a curfew.
According to state government data, 37,450 people are sheltering in 272 relief camps at present.
Deadly communal clashes erupted in Manipur in early May between the Meiteis and Kuki peoples because the Meiteis are looking for Scheduled Tribe (ST) status.
Meiteis constitute about 55 percent of the state's population, and the Kuki, who make up about 25 percent, fear that if ST status is granted to the Meiteis, they will take the lion's share of all the benefits offered to minorities in the state, including in education and the workplace.
