Dubai: Saudi Arabia says four family members have been killed by a cross-border missile from Yemen that struck their home in the southern region of Jizan.

Saudi’s Civil Defence spokesman in Jizan, Yehia Al Qahtani, said in a statement that a woman and child were among those killed in the attack and that three others were wounded and taken to a hospital for treatment.

He says the missile struck the home around 1.30am on Monday.

The shell hit Samtah, in the southwestern Saudi border region of Jizan, a tweet by the Saudi Civil Defence said.

Seven Saudi soldiers and dozens of Al Houthi fighters were killed in heavy fighting on the border with Yemen on Sunday, as the main combatants in Yemen’s war prepared for a further week of peace talks in Kuwait.

The UN-sponsored negotiations had been on the verge of collapse after a new row erupted last week between the Saudi-backed government and its Iranian-allied Al Houthi foes and renewed fighting broke out.

UN Yemen envoy Esmail Ould Shaikh Ahmad said the talks between Al Houthis and their General People’s Congress party allies and the internationally-recognised government of President Abd Rabbo Mansour Hadi had been extended by a week.

Yemen’s government on Sunday accepted a UN-proposed plan to end the fighting, but the rebels rejected it, insisting that any settlement must first tackle a unity administration.

The draft agreement stipulates that Al Houthi rebels must withdraw from Sana’a, which they overran in September 2014.

The proposed peace deal is broadly in line with the demands of Hadi’s internationally-recognised government.

It replaces a road map previously proposed by Ould Shaikh Ahmad that stipulated the creation of a unity government including the insurgents, which was rejected by Hadi’s government.

Under the new plan, a political dialogue between the factions would start 45 days after the rebels withdraw and hand over heavy weapons to a military committee to be formed by Hadi.

Prisoners of war would also be freed.

The government’s acceptance came after a meeting in Riyadh chaired by Hadi.

“The meeting approved the draft agreement presented by the United Nations calling for an end to the armed conflict and the withdrawal [of rebels] from Sana’a” and other cities they have seized, said a statement.

Yemeni Foreign Minister Abdul Malek Al Mikhlafi, who is leading Hadi’s negotiating team, said he had sent a letter to the UN envoy informing him the government backed the “Kuwait Agreement”.

One precondition, however, is that the Al Houthis and allied forces loyal to Saleh sign the deal by August 7, Mikhlafi wrote on Twitter.

The rebels rejected the proposal.

“What was presented by the (UN) envoy was no more than just ideas for a solution to the security aspect, subject to debate like other proposals,” a statement from the rebel delegation said.

It charged that the Yemeni government announcement of a draft settlement was “no more than media stunts” aimed at foiling talks.

The rebels reiterated their long-standing demand that a peace deal must first forge an accord on a new consensual executive authority, including a new president and government.

This condition is an explicit demand for the removal of the internationally recognised Hadi.

Al Houthi spokesman Mohammad Abdul Salam said on Twitter before the government announcement that the rebels insist on a comprehensive and complete peace agreement, rejecting what he called “half solutions”.

On Sunday, rebels and loyalists traded artillery fire near the Saudi border, military sources said.

The rebels angered the government last week by announcing the formation of a 10-member “supreme council” to run Yemen, which Mikhlafi branded a “new coup”.

Under the proposed peace deal, that council would be abolished and all rebel decisions since they occupied Sana’a would be rescinded.

A defiant Saleh defended the new council, which he said aimed at “filling the political void left in the country after the legitimacy of Hadi expired and he fled” to Saudi Arabia.

“This council will govern the country as a presidential council and in accordance with the country’s constitution and laws,” Saleh said.

Hadi’s government has used main southern city Aden as a temporary capital since it was recaptured from the Al Houthis last year.
