Swedeninfo-icon:- UN Secretary-General Antonio Guterres says the Yemeni warring parties have reached an agreement on a ceasefire in the Red Sea port city of Hudaydah, as a new round of peace talks aimed at ending nearly four years of a brutal Saudi-led warinfo-icon on its southern neighbor came to a close in Sweden.

The UN chief made the announcement on Thursday, shortly after the delegations of Yemeninfo-icon's Houthi Ansarullah movement and the country's former Saudi-backed government agreed that the worldinfo-icon body play a "leading role" at the vital port, which is currently controlled by the Houthis.

"There is a ceasefire declared for the whole governorate of Hudaydah in the agreement and there will be both from the city and the harbor a withdrawal of all forces," Guterres said, adding that after the pullout, the UN would begin facilitating aid access to the civilian population.

More than 70 percent of Yemen's imports used to pass through the docks of Hudaydah.

Hudaydah has, however, been placed under a tight siege since June, when the Saudi-led coalition and their allied militia loyal to the government of Yemen's ex-president, Abd Rabbuh Mansur Hadi, launched a full-scale military push to seize the strategic port city in defiance of international warnings.

Amid ongoing peace talks in Sweden, the United Nationsinfo-icon proposes that the embattled Yemeni port city be ruled by an interim 'joint committee or independent entity.'

The significant agreement came a week after the rival Yemeni sides began peace negotiations, brokered by UN Special Envoy Martin Griffiths and his team, in Rimbo, a locality near the Swedish capital of Stockholm.

The Riyadh-backed side had on Friday said the Houthis must hand over the vital port. However, Mohammed Abdulsalam, the head of the Houthi delegation at the peace talks, strongly rejected the proposal, saying that Hudaydah must be kept apart from the military conflictinfo-icon, and that a government should be formed first before all parties are disarmed.

Griffiths, for his part, said on Thursday that the pullout of all forces should take place "within days." He is due to brief the UN Security Council on Yemen on Friday.

The fate of the international airport of Sana'a, the Yemeni capital, has also been a hot issue on the agenda of the talks. The capital is under the control of the Houthis, but the Saudi led-military coalition controls Yemen's maritime borders and airspace.

The airport has been closed to commercial flights for the past nearly three years. Griffiths said its fate would be discussed at the next round of talks, which will take place at the end of January 2019, according to the UN chief.

"It's clear and it's public knowledge that starting point is opening up to commercial flights, maybe domestic at first, and eventually (international)," he added.

Guterres, who arrived in Sweden late Wednesday to attend the closing session, further announced in a press conference on Thursday that both parties had also reached a series of other breakthroughs regarding the bloody conflict in Yemen, including a "mutual understanding" on Yemen's third city of Ta'izz, another hotspot in the war-ravaged country and the scene of some of the most intense clashes between the rivals.
