A Yemeni rights group on Tuesday accused both sides in the country's civil war of arbitrary detentions, forced disappearances and torture of hundreds of people in the past four years in unofficial detention centres across war-torn Yemen.

The attack came hours after Yemeni rebels, known as Houthis, said they shot down a warplane of the Saudi-led coalition over the province of Jawf.

The deal aims to halt months of infighting between the two groups.

According to one database tracking the carnage, the country’s civil war has killed at least 91,600 people so far. 

Yemen's Houthi rebels are expected to begin their withdrawal on Saturday morning.

President Donald Trump on Tuesday vetoed a resolution passed by Congress to end U.S. military assistance in Saudi Arabia's war in Yemen.

A hospital in a rural area of northwest Yemen was hit by an airstrike Tuesday killing seven people and wounding eight others, Save the Children said.

The vote puts Congress on a collision course with Trump, who has already threatened to veto the resolution, which the White House says raises “serious constitutional concerns.”

Lawmakers accused Saudi Arabia of a litany of misdeeds and criticized its crown prince as going "full gangster."

The U.S. House wants to stop American support for the war in Yemen, but Donald Trump is likely to veto the effort.
