The UN on Tuesday called for a "humanitarian" truce in air strikes and fighting in Yemen as it seeks to deliver aid to people trapped in the capital Sanaa.

As the UN Security Council prepared to discuss Yemen on Tuesday, several international aid agencies chimed in to condemn a surge in violence in the war-torn country, and demanded unimpeded access to civilians.

"I... sent a message asking for a truce, a peace pause, a humanitarian pause, for the parties to stop shooting, stop fighting, stop air strikes, so the people can go to hospitals, can go to seek safety ... and go to also find a place for water and food," UN humanitarian coordinator Jamie McGoldrick told reporters in Geneva by phone from Sanaa.

"Our ability to get to people over the last five days has been impeded because of the air strikes, because of the fighting, and our life-saving support activities were blocked," he said.

McGoldrick's statement came a day after Yemen's Huthi rebels killed former president Ali Abdullah Saleh as he fled the capital following the collapse of their uneasy alliance.

For the five previous nights, heavy fighting had rocked Sanaa, leaving at least 234 people dead and 400 wounded, according to the International Committee of the Red Cross.

After the assassination, Saudi-led warplanes pounded the capital before dawn Tuesday as the rebels moved to consolidate their control over the city.

"What happened... because of our inability to move in the city during the five days -- the UN agencies, Red Cross and NGOs -- we were unable to do our life-saving treatments," McGoldrick said.

"Now the uncertainty continues and despite what happened yesterday, we don't know if we can start doing our operations or whether we have to wait for some time," he added.

Yemen's war has left thousands dead since 2015, sparking what the United Nations now labels the world's worst humanitarian crisis, and has deepened tensions between Middle East rivals Saudi Arabia and Iran.

McGoldrick said a UN team would travel to Riyadh "quite soon".

Saudi Arabia imposed a blockade on Yemen's ports after a Huthi missile was intercepted near Riyadh airport on November 4.

The blockade has been eased only partially despite repeated calls from the UN.

- 'Thousands in fear' -

Five major international NGOs meanwhile demanded in a statement an "immediate cessation of hostilities" in Yemen, as well as "full and unfettered humanitarian access to people in need".

The fighting and air strikes have left "thousands of people in fear, trapped in their homes and without any possibility to access humanitarian assistance", the statement said.

Signed by Care, Action Against Hunger, Handicap International, Doctors of the World and Acted, the statement said the warring parties should respect their obligations under international law and "ensure full protection" of civilians.

"A situation that is already catastrophic is only worsening day by day, and we call on the UN Security Council to exert its influence on the parties in order to bring this war to an end as quickly as possible," Handicap International's Arnaud Pont told AFP.

The statement came as the UN Security Council was meeting Tuesday to discuss the situation in Yemen.
