After representatives from Yemen’s internationally recognized government were expelled from the embassy in Qatar, Sudan’s foreign ministry has said it has agreed to represent Yemen’s interests there. Yemen cut diplomatic ties with Qatar on June 5th.

“Sudan’s Foreign Minister Ibrahim Ghandour on Tuesday received a message from his Yemeni counterpart dealing with bilateral ties, where the message included a request for Sudan to take care of the Yemeni interests in Qatar,” said Sudan’s Foreign Ministry in a statement.
