While the United Nations said the decision to relocate about half of its international staff shouldn’t be seen as a diplomatic retreat, the move comes amid concerns that Taliban fighters have been emboldened by the deadly attack and may try to strike again.

“They realize that if they hit the United Nations again, there’s a serious risk of the United Nations leaving the country,” said one diplomat in Kabul, who spoke only on the condition of anonymity so that he could speak candidly about the U.N. plans.

One of the biggest worries is that insurgents in Afghanistan are trying to duplicate the strategy of Iraqi extremists who forced the United Nations to shutter its Iraqi operations in 2003 after a devastating truck bomb hit the U.N. headquarters, killing 22 people, including the top U.N. official in the country.

If the U.N. were to pull out of Afghanistan, it would force all other international aid groups to rethink their work in the country and undermine President Hamid Karzai’s shaky government.

“That’s the name of the game: Get the U.N. out,” the diplomat said. “If they can get the United Nations out, then they think they can take out the Karzai government.”

Kai Eide, the Norwegian diplomat who heads the U.N. mission in Afghanistan, said there were no plans to abandon the country.

“We are not talking about pulling out,” Eide said at a news conference in Kabul. Instead, he said, the U.N. is going to relocate hundreds of international workers while it figures out how to protect the staff better.

The United Nations has about 1,200 international staff members in Afghanistan. About 600 nonessential staff will be relocated temporarily to other parts of Afghanistan or to nearby regional offices, said Aleem Siddique, a spokesman for the U.N. operation in Afghanistan.

Currently, much of the staff lives in a well-known network of guesthouses — small, lightly guarded compounds — spread out across Kabul.

Last week, three militants exploited the vulnerability of the guesthouses by scaling the walls of one compound and staging an attack that killed five people.

Afghan officials said six men had been arrested and accused of planning the attack.

Over the next four to six weeks, Siddique said, the U.N. will search for ways to consolidate its housing to reduce the dangers.

“We are not going to be deterred by the threats of terrorist and extremists,” Siddique said. “We have no intention of leaving any time soon.”
