British Prime Minister David Cameron put Sri Lanka on notice Saturday to conduct an "credible, transparent and independent" investigations into allegations of war crimes by March or else he would lead a push for action at the United Nations.

But Sri Lanka remained defiant, with government ministers dismissing Mr. Cameron’s warning as “nothing new” and accusing him of interfering with Sri Lanka’s sovereignty.

"Tamil journalists, who had gone to reporting the intentional disruption by authorities of peaceful demonstrations held by family members of missing persons and Tamil people demanding justice, were threatened by individuals believed to have been members of the security forces dressed in civil clothing, further illustrating that intimidation of Tamil journalists continues to take place on the island."

“Is it not sad? Who is to blame? I wanted my PM to go there first. I was the second Indian foreign minister to go there [after the war]. But who do I blame for it? I am only disappointed that I could not take the Prime Minister to an area where we are building 50,000 houses. We can’t show him this and the roads and projects that we are building [in Jaffna],”

The newly elected member of the Northern Provincial council, Ananthy Sasitharan, in an interview with Journalists for Democracy, outlined  attacks on families of the disappeared when they attempted to stage demonstrations in front of the David Cameron.

Describing the attacks Ms. Sasitharan, who received the second highest number of votes in the Northern Provincial elections, said,

“When we tried to wave flags and chant slogans, the anti-riots squad police personnel unleashed waves of brutal attack on us. They beat us with batons and kicked us with boots on. Even the Catholic priests and wailing elderly mothers of the disappeared were badly assaulted as the VIPs were going past as mere onlookers.”

“As part of our support for reconciliation efforts across this country, we will provide an additional £2.1 million to support demining work in Jaffna, in Kilinochchi and in Mullaitivu districts – the location of some of the most chilling scenes from Channel 4’s No Fire Zone documentary.”

Several journalists were prevented from entering the final press conference of the Commonwealth Heads of Government Meeting, Saturday.

"Never in 40 years of Commonwealth summits has a British Prime Minister faced such a diplomatic showdown with a host leader as Mr Cameron faces."

“The images in that film [No Fire Zone] are completely chilling... It’s an appalling set of allegations and of course these allegations have been backed up by the work of the UN Special Rapporteur who has had them verified."

“These are chilling images of appalling acts and they need to be properly investigated.”

"There are legitimate accusations of war crimes that need to be properly investigated"

"How on earth is it right that that man and that coutry is able to chair an important organisation like the Commonwealth and welcome you as Prime Minister of the United Kingdom?"
