MANILA -- Measures introduced by the Philippine government to curb human rights abuses are mere "window-dressing," an official from Human Rights Watch said Thursday.

"The list of actions touted by the Philippine government as progress unfortunately seem little more than window-dressing," said Elaine Pearson, Asia deputy director for the New York-based rights group.

Although the government has said extra-judicial killings fell sharply last year, Pearson said a "pause in political killings will mean little in the long run unless those responsible are prosecuted."

She told reporters in Manila that the government's failure to convict military men for human rights abuses will be brought up during a review of the Philippines at the UN Human Rights Council in Geneva on April 11.

Pearson said Human Rights Watch (HRW) research showed that since 2001, there had been hundreds of cases of suspected insurgents, leftists, reporters, government critics and activists who had been murdered or had vanished, but no military man had been convicted of these crimes.

Although the government had set up a task force to investigate these incidents and had put in place measures to protect witnesses in these cases, these actions had "in fact accomplished little, and seem designed to merely deflect domestic and international criticism," Pearson added.

"Human Rights Council members should be asking the government why it hasn't taken strong action against abusive military personnel that would finally put a stop to these killings," said Pearson.

She noted that UN Special Rapporteur Philip Alston, following a visit to the Philippines in February 2007, said the military was in denial about the killings.

She said HRW had already submitted its findings to the council in Geneva and they would be taken up at the review session next month.

"The Philippines is among the first countries up for the universal periodic review, and as such it will be a test for the Human Rights Council," said Pearson.

She said the United Nations would not seek sanctions against any of the countries concerned but said the session "would help focus attention on the serious concern on the human rights problem in the Philippines."

"We hope to apply peer pressure on the Philippines," she said.
