Suicide attackers hit U.N. compound in Afghanistan

Suicide attackers burst into the main United Nations compound in the western city of Herat on Saturday, setting off a battle with Afghan police and troops. All four assailants were reported killed, but the U.N. said there were no casualties among its staff.

The incident roiled the aid community in Afghanistan at a time when a number of international humanitarian and development groups are considering curtailing or halting projects in response to an upcoming ban by President Hamid Karzai on the use of private security guards. Western diplomats are pressing the Afghan leader to ease the restrictions, which are to take effect at the end of the year.

The attack in Herat, the biggest city in western Afghanistan, began with a detonation at one of the complex’s entry gates, according to provincial officials, and three assailants then managed to push their way inside. One or more of them wore a burqa, or a body-length veil, said Naqib Armin, a spokesman for the provincial governor.

The compound, on the city’s edge near the airport, houses several U.N. agencies which employ both foreign and Afghan staff. There would have been about 40 people inside at the time, said U.N. spokesman Dan McNorton.

One of the attackers was killed at the outset of the strike when he set off explosives inside a car, provincial authorities said. Two others apparently detonated their suicide vests, and the last was shot dead by police.

Herat province is considered a relatively calm part of the country -- so much so that it is being considered as one of the first places where the NATO force will attempt to hand over security responsibility to Afghan forces.

With Western military officials claiming major success in driving the Taliban from strongholds in Kandahar province, however, the insurgency has been making a push into parts of the country that were previously considered relatively safe, such as the north.

Attacks inside Kandahar have diminished since the Western military offensive began in earnest about a month ago, but insurgents are still able to move about despite the security cordon around the city. A motorcycle-borne suicide bomber at a main traffic circle in the city killed one passerby and injured two others on Saturday, provincial authorities said.

Outside Kandahar city, veteran New York Times photographer Joao Silva was seriously injured Saturday when he stepped on a buried bomb, the newspaper reported on its website. Although NATO officials say Taliban fighters have been mainly driven out of the district, Arghandab, the insurgents have seeded the area with IEDs, or improvised explosive devices, which are the principal killer of Western troops.

Most of the 30,000 American troops who arrived this year under President Obama’s “surge” are deployed in the south, mainly in Helmand and Kandahar provinces.

NATO troops were not involved in responding to the attack in Herat, said Lt. Col. Regina Winchester, a spokeswoman for the International Security Assistance Force. However, witnesses said Western forces were seen helping cordon off the scene, and a NATO helicopter circled overhead. NATO troops in the west of Afghanistan are under Italian command.

McNorton, the U.N. spokesman, said it was “too early to speculate” about steps the world body might take in response to the attack on its compound. The U.N. sent hundreds of foreign staffers out of the country after a Taliban attack last October on a U.N. guesthouse in the capital, in which five of its foreign staff were killed.

This year has been a perilous one for foreign aid workers in Afghanistan. In August, insurgent gunmen killed a 10-member medical team, including six Americans, in Badakhshan province, in the north. Earlier this month, a Scottish development worker was killed during an attempt by American troops to rescue her after she was abducted by the Taliban.
