KABUL, Afghanistan (AP) – American-led coalition and NATO forces fighting insurgents in Afghanistan have killed at least 203 civilians so far this year – surpassing the 178 civilians killed in militant attacks, according to an Associated Press tally.

Insurgency attacks and military operations have surged in recent weeks, and in the past 10 days, more than 90 civilians have been killed by airstrikes and artillery fire targeting Taliban insurgents, said President Karzai.

On Sunday, another civilian may have been killed when British troops opened fire in a populated area after their convoy was hit by a roadside bomb, officials and witnesses said.

Separate figures from the U.N. and an umbrella organization of Afghan and international aid groups show that the numbers of civilians killed by international forces is approximately equal to those killed by insurgents.

After a seething speech by Mr. Karzai on Saturday – in which he accused NATO and American forces of viewing Afghan lives as “cheap” – NATO conceded that it had to “do better.” Coalition spokesman Major Chris Belcher suggested that some civilians reportedly killed by foreign forces may in fact have been killed by insurgents.

“One of the problems is sometimes determining who exactly caused the casualties. It’s not always clear if a civilian casualty is caused by an extremist or coalition forces,” Major Belcher said.

Accurate figures for civilian death tolls are hard to come by in Afghanistan, where militants often wear civilian dress and seek shelter in villagers’ homes. Furthermore, after a quarter of a century of civil war and conflict, it is not unusual for Afghans to have weapons in their homes.

Much of the violence takes place in remote areas that are too far or too dangerous for independent observers or journalists to reach for verification of the reports.

The AP count of civilian casualties is based on reports from Afghan and foreign officials and witnesses through Saturday. Of the 399 civilian deaths so far this year, 18 civilians were killed in crossfire between Taliban militants and foreign forces.

America and NATO did not have civilian casualty figures. The U.N. Assistance Mission in Afghanistan has counted 213 civilians killed by insurgents in the first five months of this year – compared to 207 killed by Afghan and international forces.

ACBAR – the Agency Coordinating Body for Afghan Relief – has counted 230 civilians killed in U.S. and NATO operations, basing their figure on reports from the Afghan Independent Human Rights Commission, Afghan NGO Security Office and the U.N.

The number of civilians killed in militant attacks was approximately the same as those killed by foreign forces according to ACBAR’s latest figures from about a month ago, said Anja de Beer, director of ACBAR.

“The international forces are here to support the Afghan government, the purpose is to get a better and safer life for the Afghan people,” Mr. de Beer said. “If in doing so, they’re causing more civilian deaths than the people they’re fighting against, that doesn’t look very good, to put it mildly.”

Majpr John Thomas, a spokesman for NATO’s International Security Assistance Force, blamed the insurgents for hiding in areas populated by civilians, who are then killed during attacks against militants, but he said “that does not absolve ISAF of the responsibility of doing all it can to minimize civilian casualties.”

On Saturday, Karzai accused NATO and American-led troops of carelessly killing scores of Afghan civilians and warned that the fight against resurgent Taliban militants could fail unless foreign forces show more restraint.

“Afghan life is not cheap and it should not be treated as such,” Mr. Karzai said angrily.

The mounting toll is sapping the authority of the Western-backed Afghan president, who has pleaded repeatedly with American and NATO commanders to consult Afghan authorities during operations and show more restraint.

Mr. Karzai also denounced the Taliban for killing civilians, but directed most of his anger at foreign forces.

In one of the recent incidents lamented by Mr. Karzai, police said NATO airstrikes killed 25 civilians along with 20 militants who fired on alliance and Afghan troops from a walled compound in the southern province of Helmand.

On Sunday, Helmand provincial police chief Mohammad Hussain said British gunfire killed one man after the troops were attacked, but it was not clear if the victim was a civilian or a militant involved in the attack.

Raz Mohammad Sayed, director of a local hospital, said one man was killed, and another man was wounded by British gunfire. He referred to both victims as “civilians.”

NATO blames the insurgents for hiding among civilians, and insisted that troops had the right to defend themselves.

“If someone’s firing at me, he’s a combatant,” Major Thomas said.

Another NATO spokesman, Nicholas Lunt, said, “We need to do better than we have been doing so far. But unlike the Taliban, we do not set out to cause civilian casualties, and that is a critical difference.”

Earlier Saturday, Pakistan said a rocket hit a house in Pakistani territory killing nine civilians during a battle in which NATO and American-led forces killed some 60 suspected Taliban near Afghanistan’s eastern border.

Other fighting reported Saturday left some 20 militants and one coalition soldier dead. The soldier, who died in a gunbattle in the southern province of Helmand, was not further identified.
