The 24-hour curfew in Swat Valley, North West Frontier Province, which started on May 18, has led to severe shortages of food, water and medicines, creating a humanitarian crisis, according to Human Rights Watch (HRW). "People trapped in the Swat conflict zone face a humanitarian catastrophe unless the Pakistani military immediately lifts a curfew that has been in place continuously for the last week," Brad Adams, HRW's Asia director, said in a statement.

A single American Special Forces group was behind at least three of Afghanistan's worst civilian casualty incidents, The Independent has learnt, raising fundamental questions about their ongoing role in the conflict.

Human Rights Watch (HRW) on May 13 called on the US government to make "fundamental changes to reduce civilian casualties" in Afghanistan after attacks last week reportedly left more than 140 civilians dead. HRW said that a review announced by chief of the US Central Command General David Petraeus must result in "measures that genuinely minimize civilian loss of life." HRW called on the US to heed international laws of war, under which attacks cannot be indiscriminate or cause disproportionate civilian loss.

Among the tens of thousands who have fled their homes in Swat Valley and the adjacent Buner district of Pakistan's North West Frontier Province (NWFP) are about 2,000 Sikhs who have taken refuge in a Sikh shrine in Hasanabdal, a town about 50 kilometers from Pakistan’s capital, Islamabad. According to Gulbeer Singh, head priest at the Sri Punja Sahib shrine, about 207 families from Buner District and 96 from Swat had taken refuge there. The number of Sikh internally displaced persons (IDPs), he said, is roughly 2,000.

The US announced May 11 the replacement of its commander in Afghanistan, Gen. David McKiernan, with Lt.-Gen. Stanley McChrystal, a former chief of Pentagon special operations forces. "Our mission there requires new thinking and new approaches from our military leaders," said Defense Secretary Robert Gates. (AlJazeera, May 11)

A US military contractor who pleaded guilty in February to voluntary manslaughter for the 2008 shooting of an Afghan detainee was sentenced in the US District Court for the Eastern District of Virginia May 8 to five years probation and a $12,500 fine. Don Ayala had been charged with second-degree murder for shooting and killing detainee Abdul Salam in retaliation for Salam's earlier attack on Ayala's fellow contractor Paula Lloyd.

Gen. David McKiernan says the mission in Afghanistan is likely to fail if militants continue to gain power in Pakistan. During a press briefing, the commander of the US forces in Afghanistan said, "Can you get to the right end-state in Afghanistan if you have a deteriorating or failed state in Pakistan? The answer is probably no."
