United Nations, Aug 10 (IANS): The UN Security Council has expressed grave concern over what it said was a serious deterioration of the economic and humanitarian situation in Yemen amid worsening security, including the threat from Al Qaeda in the Arabian Peninsula.

In a press statement, the Council urged all parties in Yemen to ensure that those in need of humanitarian assistance can be reached, voicing concern over the increasing interruption of the flow of basic supplies. The United Nations body also urged all parties to refrain from targeting vital infrastructure.

"The members of the Security Council urged all sides in Yemen to reject violence and show maximum restraint," said the statement, read to reporters by Hardeep Singh Puri, Permanent Representative of India, which holds the Council's rotating presidency this month.

"They called upon all the parties to respect their obligations under applicable international law."

The Council also called on all parties to urgently seek a solution to the crisis in an inclusive, orderly and Yemeni-led process of political transition that meets the needs and aspirations of the Yemeni people for change. It took note of the inter-Yemeni efforts in that regard, saying the Gulf Cooperation Council's (GCC) initiative continues to be important.

The Council welcomed the efforts of the Good Offices of the Secretary-General through his Special Adviser, Jamal Benomar, and those of the GCC. The statement was issued following a briefing to the Council by Benomar.

In a separate press statement the Security Council condemned in the strongest terms the attack on UN peacekeepers in Darfur Aug 5, which resulted in the death of a Sierra Leonean soldier and left another seriously wounded.
