The United Nations has encouraged some non-essential staff to leave Afghanistan amid security concerns ahead of elections later this month.
A UN spokesman said some of the body's agencies had urged some employees to take their leave during the elections because of fears of violence, although he noted that the official UN alert level had not changed.
Emma Sutcliffe, a UN Development Program communications associate, said "We have been encouraged to take rest, but it's not mandatory."
"For those who remain behind, there'll be minimal movement," she said.
Other UN agencies, including the World Food Program and the UN High Commissioner for Refugees, said they had not increased their security precautions.
News that some UN staff were being encouraged to leave came after an Interior Ministry spokesman warned of more attacks.
"They (militants) focus on soft targets, attacking candidates, burning schools, aid workers," he said. "But the security workers have also taken necessary measures to provide needed security."
Some of the latest violence has been against foreigners, including the killing of a kidnapped British engineer and the separate killings of two Japanese teachers.
