DUBAI — A Houthi drone strike on Yemen's Marib province killed three members of government forces Friday, a Yemeni military source said, as the rebels escalate strikes on the key oil-rich province a day after their deadliest attack in years.

 

"Three killed and four wounded in a preliminary toll from the Houthi drone attack on the Harib area, in the south of Marib," the source said, requesting anonymity to discuss sensitive matters.

 

The Houthis have launched "more than 10 missiles and seven suicide drones targeting military camps in Marib", he added.

 

The official had earlier told AFP that artillery exchanges and clashes were taking place in Sirwah and on the Al-Kasara front, north of Marib city, where Houthi drones were spotted.

 

The rebels also hit an arms depot in the province.

 

Strategic Marib is split between the Houthis and the government, which controls the city of the same name as well as the oil fields and facilities.

 

The Houthis in 2021 resumed an offensive seeking to take the oil-rich province, but the fighting was largely halted after the nationwide truce was agreed in 2022.

 

On Thursday, the Iran-backed rebels killed at least 58 government troops in missile and drone attacks, some in Marib, a military source said, in one of the deadliest incidents between the two sides in years.

 

Yemen, which has been embroiled in more than a decade of war, last month became the latest front to be sucked into the US-Iran conflict, as the Tehran-backed Houthis upended the 2022 truce.

 

The rebels welcomed an Iranian plane directly to the Yemeni capital Sanaa, triggering a series of tit-for-tat attacks, and later announced a maritime blockade of Saudi Arabia and began hitting its tankers.

 

Last month, the Houthis killed 16 troops in an attack on government-aligned forces south of the port city of Hodeidah, two medical officials told AFP.
