The State Department has closed the U.S. Embassy in Yemen and evacuated its staff, including the ambassador, amid a political and security crisis in the capital Sana’a. Yemen has been in limbo since Houthi rebels forced the resignation of the Yemeni cabinet and then seized power last week. Speaking to reporters in Washington, State Department spokesperson Jen Psaki declined to share details on the closure.

Jen Psaki: “The safety and security of U.S. personnel in Yemen is our top priority, and we are always evaluating the security situation on the ground and taking steps to mitigate risks. We have been reducing staff in Yemen over the past few weeks, as all of you know, given the volatile political and security situation. We have nothing further to announce over and above what we have previously announced.”

The Houthis have dissolved parliament and named Mohammed Ali al-Houthi as the new president in place of the ousted Abdu Rabbu Mansour Hadi. The Houthis’ moves come as they take part in a new round of U.N.-brokered talks.
