In a statement released on Tuesday, Ban called on all parties to the Yemeni conflict “to take all feasible precautions to avoid loss of civilian life and damage to civilian objects.”

At least 32 Yemenis were killed in Saudi airstrikes on various residential locations throughout the capital Sana'a Tuesday. A school was also hit in the strikes.

Ban also urged all Yemeni warring factions “to work with his Special Envoy for Yemen, Ismail Ould Cheikh Ahmed, in the search for a durable political solution.”

The UN chief further welcomed the recent release of six foreign nationals by Yemen’s Ansarullah Houthi fighters, saying “this measure represents a concrete and positive step in efforts to lessen tensions in the region and ease the path to a peaceful settlement to the conflict in Yemen.”

The hostages, including two Americans, three Saudis and a British citizen, were released on Sunday and later flown from Sana’a, to neighboring Oman.

Saudi Arabia launched its military aggression against Yemen on March 26 – without a United Nations mandate – in a bid to undermine the Houthi Ansarullah movement and restore power to Abd Rabbuh Mansur Hadi, fugitive former president and a staunch ally of Riyadh.

According to a report released on September 19 by the Yemen’s Civil Coalition, over 6,000 Yemenis have so far lost their lives in the Saudi airstrikes and a total of nearly 14,000 people have been injured; Press TV reported.
