The termination of US support in the Yemen conflict will therefore fulfil one of Joe Biden's presidential pledges.
During his speech, Biden will reportedly pick Timothy Lenderkin to serve as his special envoy for Yemen, who will be tasked with encouraging the warring sides to take steps toward a ceasefire.
Yemen has been embroiled in a prolonged conflict between government forces led by President Abd Rabbuh Mansur Hadi and the Houthi rebels since 2014.

The United Nations considers Yemen the world’s worst humanitarian crisis, with more than 80 percent of the population, or 24.1 million people, in need of assistance.
The US Department of State earlier initiated a review of the designation of the rebel Houthi movement as a terrorist organisation - a step undertaken by the outgoing Trump administration in early January.
