The United States special envoy to Yemen has said Washington is “aggressively” using back-channel discussions to speak to the leadership of the Houthi rebels in an effort to end the war that began in 2014. Al Jazeera reports that the former administration of President Donald Trump, which maintained close relationships with Saudi Arabia and the UAE, labelled the Iran-aligned Houthis a “terror” organisation, which the Biden administration rescinded on Tuesday. The administration has also said it ended offensive support of the Saudi Arabia-led forces in Yemen, though exact details remain murky.
