"We are pleased to see the resolution that calls for the establishment of a truce," Foreign Ministry spokesman Hamid RezaAsefi told reporters.

However, "we believe that the mass killing of the Lebanese should have been prevented much earlier," he said, adding that a delay in the adoption of the resolution by one month has impaired the credit of the UN Security Council.

"But since the Lebanese government and (Hezbollah chief) Mr. (Hassan) Nasrallah have accepted the ceasefire proposal, we are also satisfied," Asefi said.

The UN Security Council on Friday unanimously adopted the resolution that calls for Israeli withdrawal and authorizes an increase of the existing UN force in Lebanon to 15,000 troops to help Lebanese troops take control of south Lebanon as Israel withdraws.

The resolution calls for a "full cessation of hostilities based upon, in particular, the immediate cessation by Hezbollah of all attacks and the immediate cessation by Israel of all offensive military operations."
