Iranian Foreign Minister Mohammad Javad Zarif warned Saudi Arabia on Tuesday not to deploy troops in Syria, saying it would violate international law, while also demanding that Riyadh stop bombardments in Yemen.

Zarif was questioned about Saudi Arabia's announcement that it could deploy ground forces as part of the US-led coalition fighting the terrorist group of ISIL.

"Those who are operating in Syria without the authority of the sovereign government in Syria are violating international law," he told a news conference at the European Parliament in Brussels.

Speaking later after a meeting with his Belgian counterpart Didier Reynders, Zarif added: "We believe that's dangerous... I believe everybody should put forces together to find a peaceful solution, not to create more danger and more hostility in the region."
