Amman, July 23 (Petra) - European Union (EU) High Representative for Foreign Affairs and Security Policy Kaja Kallas called on Yemen's Houthis to stop their attacks on Red Sea vessels following a strike on a Saudi oil tanker, according to Agence France-Presse (AFP).

Kallas denounced the attack as "illegal and unacceptable," warning that such assaults further inflame already heightened regional tensions.
