Turkish foreign minister Hakan Fidan said Turkey was assessing how it can help Saudi Arabia, but ruled out troop deployment and Turkish participation in offensive operations. (Gambar Bernama)ANKARA: Turkey, Pakistan, Egypt and Saudi Arabia condemned attacks by Yemen's Iran-backed Houthi militants on Riyadh's international airport, saying they were a "dangerous escalation that cannot be justified or accepted under any pretext".

One person was killed and nearly a dozen hurt in a new attack on Riyadh's international airport on Sunday, Saudi authorities reported, a day after a strike claimed by the Houthis that killed 13 people and wounded more than 300.

The group of regional powers -- dubbed the R4 -- reaffirmed their solidarity and support for Saudi Arabia, including full support for all "legitimate measures and steps" it takes to counter the attacks, deter threats and prevent them from happening again.
