The Arab coalition battling Iran-backed rebels in Yemen has provided pro-government forces in the besieged city of Taez with dozens of armored vehicles, military sources and Emirati media reported Monday.

The coalition has sent 30 military vehicles, including tanks, to forces loyal to President Abdrabbu Mansour Hadi in Taez, the southwestern gateway to the rebel-held capital, military sources there told AFP.

Meanwhile, 12 pro-government fighters, part of a 500-strong Yemeni force sent from the main southern city of Aden, were killed in a late Sunday ambush by the rebels en route to Taez, military sources and medics said.

Abu Dhabi-based The National paper said that “UAE-supplied military vehicles have arrived at the front line of the battle for the city of Taez,” adding that “dozens” of armored vehicles were delivered on Sunday to pro-government fighters in the city.

The United Arab Emirates has played a key role in the Saudi-led coalition which has been battling rebels in Yemen since March.

Taez has remained in the hands of fighters loyal to President Hadi. But the Shiite Houthi rebels and their allies have besieged it for months with clashes raging between rival forces.

The Dubai government-owned daily Al-Bayan reported that “coalition forces, reinforced by vehicles and modern arms… have deployed in Taez.” But The National and military sources said that the armored vehicles were manned by Yemeni fighters.

UAE media reported that more reinforcements are expected to arrive in Taez from Lahj province in the south.

The modern weapons provided by the coalition include US-made anti-tank TOW missiles, according to the Asharq Al-Awsat daily.

Last week, the coalition dropped arms and ammunition to pro-government fighters in Taez, military sources said.

Coalition support by troops and arms to loyalists in Aden helped them press on with a July offensive that pushed the rebels out of Aden and four other southern provinces.

The Saudi Press Agency announced late on Sunday that one of the Kingdom’s guards was killed in cross-border fire from Yemen.

More than 70 people have been killed in Saudi Arabia from border shelling and skirmishes since the coalition campaign began. Soldiers have accounted for most of the border casualties.

The UAE has lost 68 soldiers fighting as part of the coalition.

The Houthis overran Sanaa in September 2014 and went on to seize control of several regions, aided by forces loyal to ousted president Ali Abdullah Saleh.
