The US is to designate Yemen’s Houthis as a foreign terrorist organisation following a series of attacks on tankers in the Red Sea.

US secretary of state Mike Pompeo the move will provide “additional tools” to confront terrorist activity and terrorism in the Gulf region.

He said the US also intends to designate three of Houthis’ leaders, Abdul Malik al-Houthi, Abd al-Khaliq Badr al-Din al-Houthi, and Abdullah Yahya al Hakim as specially designated global terrorist (SDGT) entities.
