The United Nations condemned on Monday armed drone and ballistic missile attacks on Saudi Arabia, claimed by the Iran-backed Houthi militias in Yemen, UN spokesman Stephane Dujarric said.
"We urge all parties to abide by their obligations under international humanitarian law," he told reporters.
"It's really quite simple - such actions are detrimental to the mediation efforts being carried out by our special envoy Martin Griffiths."
