130 fighters killed amid fierce clashes between Yemeni government forces and Houthi rebels

Two days of fierce clashes between Yemeni government forces and the country’s Houthi rebels over a crucial central city have killed more than 130 fighters, mostly rebels, officials said on Tuesday.

The escalation of fighting over the energy-rich city of Marib comes as US President Joe Biden’s national security adviser Jake Sullivan travelled to Saudi Arabia to meet with Crown Prince Mohammed bin Salman as Washington presses for a cease-fire in Yemen’s war.

Yemen has been plagued by civil war since 2014, when the Iran-backed Houthis captured the capital of Sana’a and much of the country's north, forcing President Abed Rabbo Mansour Hadi and his government to flee to the south, then to Saudi Arabia.

A Saudi-led coalition entered the war in March 2015, backed by the United States, to try to restore Hadi to power. 

Despite a relentless air campaign and ground fighting, the war has deteriorated largely into a stalemate and spawned the world’s worst humanitarian crisis.

The rebels renewed their attacks on Marib earlier this year, an offensive that threatens to exacerbate a dire situation in a city that already hosts hundreds of thousands of displaced Yemenis. 

The Houthis have for years attempted to take Marib to complete their control over the northern half of the country but have met with stiff resistance.

The latest fighting has taken place south of Marib where the rebels are trying to break the government defences, according to tribal elders, government and rebel officials. The officials spoke on condition of anonymity because they were not authorized to brief the media and the elders spoke anonymously because they feared reprisals.

The rebels usually attack with waves of fighters charging government lines, thereby becoming easy targets for warplanes of the Saudi-led coalition. 

The Houthi media office said the Saudi-led coalition launched more than 30 airstrikes on their fighters around Marib on Monday.
