The Philippines (search) worked Friday to meet the demands of kidnappers holding a Filipino truck driver, withdrawing a further 11 troops from Iraq (search).

The Filipino soldiers drove over the border into Kuwait in three vehicles about 8 p.m., said Lt. Col. Hashem Abdullah, an Iraqi officer at the border town of Safwan. The troops were seen off by a delegation of U.S. troops, he said.

Their exit reduces the Philippines' troop strength in Iraq to 32, said Philippines Foreign Secretary Delia Albert, who said the head of the humanitarian mission also would be withdrawn. The pullout came despite criticism from the United States and Australia, who said the Philippines was sending the wrong signal to terrorists.

Al-Jazeera broadcast a video Thursday showing hostage Angelo dela Cruz (search) thanking the Philippines for the decision and no longer wearing the bright orange garment he wore in previous videos — an apparent sign that he is no longer under threat of death.

The Philippines had planned to pull its troops out by Aug. 20, but said Wednesday it would withdraw them early because of the kidnapping.

The decision was cheered at home but criticized by other members of the U.S.-led coalition.

"I don't want to be harsh on a friend, but it is a mistake and it won't buy them immunity," Australian Prime Minister John Howard said Friday. "It's a wretched state of affairs, but if you give in, it won't stop it happening again. You invite people to do it with increasing severity because they will know they succeed."

"If you give in, the game's over and they will increase the intensity of their attacks," he said.

White House press secretary Scott McClellan said Thursday the decision "sends the wrong signal to terrorists."

But in the Philippines, family members thanked President Gloria Macapagal Arroyo (search) and lawmakers defended her decision.

"The United States will understand that any action on the part of the government would have our national interest as our primary consideration," Senate President Franklin Drilon told reporters.

"This is a judgment call on the part of the president," he said. "No foreign policy is altruistic."

Meanwhile, a decapitated body in an orange jumpsuit was found in the Tigris River in northern Iraq, the military said Thursday. There were suspicions it could be that of a Bulgarian driver taken hostage recently by Jordanian militant Abu Musab al-Zarqawi's terrorist group and slain.

Interim Prime Minister Iyad Allawi appealed to foreign governments to stand fast. Iraq's fledgling security forces are deeply dependent on the 160,000-member multinational force — led by the United States — for assistance in maintaining order.

"We hope and wish that all civilized countries and the international community, our neighbors and brothers in the Islamic world, close ranks really to fight terrorism, because God forbid any place they gain or they win is a disaster for the world on a global level," Allawi said.

In Baghdad, an explosion targeting a U.S. military convoy ripped through a residential neighborhood on Friday, the U.S. military and witnesses said. At least four Iraqi civilians were injured in the blast, said Iraqi Police Maj. Hashem Dawoud. No U.S. soldiers were reported injured.

Also Friday, attackers using machine guns and rocket-propelled grenades fired on an Iraqi police patrol, killing one and wounding another, police officer Ammar Naji told Associated Press Television News.

Iraqi authorities also forcibly removed members of a hard-line Shiite militia from a building that they were occupying illegally in Diwaniyah, 100 miles south of the capital, the U.S. military said Friday.

Members of the militia linked to Shiite cleric Muqtada al-Sadr (search) were ordered out of the building by the provincial governor. When they did not comply, the governor ordered Iraqi National Guard and police forces to evict them, said Maj. Neal O'Brien of the 1st Infantry Division. U.S. troops provided security for the area from outside.

Al-Sadr's group has recently worked to bolster its credentials among other Shiite clerics by distancing itself from overt calls to arms and by eyeing a possible political role in the upcoming general elections in January.
