Police say Indian forces have arrested more than a thousand protesters in Indian-controlled Kashmir in an attempt to stem violent demonstrations in the Himalayan region.

Inspector-General Syed Javaid Mujtaba Gillani said the arrests were made over the past two weeks in a bid to end a month of protests in which more than 55 civilians and two policemen have been killed and thousands injured.

Kashmir has been under a security lockdown and curfew since the killing of a popular rebel commander on July 8 sparked some of the largest protests against Indian rule in recent years.

Meanwhile in New Delhi, opposition lawmakers on Monday questioned Prime Minister Narendra Modi's silence over the situation in Kashmir and demanded that the government take political steps to defuse the crisis.
