New York, July 18 - The Manipur government should act to end a cycle of unpunished violence, including killings, by security forces and armed groups, Human Rights Watch said Saturday.

Human Rights Watch said that urgent action was needed to support this process by repealing the Armed Forces (Special Powers) Act, which critics say has facilitated serious security force abuse for years.

'The situation in Manipur is nothing less than a breakdown in the rule of law,' said Meenakshi Ganguly, South Asia researcher at Human Rights Watch.

'Repealing the Armed Forces Special Powers Act would help to put an end to the abductions, torture and killings, and help restore people's confidence in the government.

'Unexplained killings attributed to the security forces or armed groups have become common in an increasingly lawless Manipur,' said Ganguly.
