The United Nations said on Monday it was pulling non-essential personnel out of Syria because of the intensified violence there, DPA reported.
The UN mission in Syria has also decided to suspend all activities on the ground, said UN spokesman Martin Nesirky.
"The situation in Damascus in particular, but also across the country, has become more precarious," he said.
Nesirky said leaders of the UN mission in Damascus were to meet to assess the situation and decide who among the personnel should leave Syria.
