DUBAI: Yemen's Houthi rebels have made important gains in the battle for the government's last northern stronghold, advancing close to the center of Marib city despite heavy casualties, military sources said yesterday. The rebels have taken full control of the northwest Kassara battlefield and made progress on western frontlines despite airstrikes by the Saudi-led coalition which backs Yemen's government, the loyalist military sources said.

Marib and its surrounding oil fields make up the last significant pocket of government-held territory in the north, the rest of which is under rebel control, including the capital Sanaa. Fierce fighting has left at least 65 dead over the past two days alone, including some 26 loyalist personnel, among them four officers, the government sources told AFP. The Iran-backed Houthis rarely disclose their own losses.

With the Houthis taking control of the Kassara front, the battles have moved to the Al-Mil area, which is a mere six kilometers (four miles) from the center of Marib and its population centers, they said. However, mountains around Al-Mil remain a formidable barrier to the rebels who launched their fierce campaign for Marib city in February. The government sources said the Houthis had poured in hundreds of reinforcements in recent days to achieve the gains, resorting to motorbikes after the coalition targeted their military vehicles.

Camps overflowing

The loss of Marib would be a major blow for the Yemeni government and for Saudi Arabia which has supported its militarily since March 2015, after the rebels captured Sanaa. Observers say the Houthis are intent on capturing the city in order to gain leverage before entering into any negotiations with the government, amid a US push to revive peace talks.

The city's fall could also lead to a humanitarian disaster, as vast numbers of civilians displaced from fighting elsewhere have sought refuge in the area. Around 140 camps have sprung up in the surrounding desert to provide basic shelter for up to two million displaced, according to the Yemeni government. Hundreds of combatants have been killed since the large-scale offensive began, with the toll fuelled by wave after wave of Houthi fighters arriving on frontlines around the city.

A government commander told AFP in Marib earlier this month that the Houthis are deploying young recruits, many of them children, with the goal of wearing out loyalist forces and depleting their ammunition. These recruits are used in first wave attacks, followed by a more lethal wave of experienced Houthi fighters under the cover of constant shelling, the commander said of a rebel strategy that is heaping pressure on loyalist forces. The escalation in hostilities has displaced 13,600 people in Marib this year, according to the UN refugee agency, putting a heavy strain on the city in the midst of a second coronavirus wave.

Lacking clean water and electricity, makeshift settlements are overflowing and camp residents say they have repeatedly come under Houthi shelling. The rebels have also stepped up missile and drone strikes against neighboring Saudi Arabia in recent months, demanding the opening of Yemen's airspace and ports. They have rejected a Saudi proposal for a ceasefire. The US administration of President Joe Biden is mounting a renewed push to end the conflict, warning that the suffering will only end when a political solution is found. - AFP
