Negotiations continued on Sunday over a United Nations Security Council vote slated for Monday morning on a British-drafted resolution that would commit to future action against Tehran and condemn Iran for providing missiles and drones to the Houthi rebels in Yemen.

However, over the weekend Russia submitted a rival text, aimed at blocking action against Iran.

Yemen has been engulfed by civil war since 2015, when the Houthis clashed with forces loyal to government of Abdrabbuh Mansur Hadi.

A multinational coalition led by Saudi Arabia intervened in March 2015, and Saudi-led airstrikes have been met by sporadic missile attacks from Houthi forces at Saudi Arabia.

This month, independent experts from the UN found that ballistic missiles fired from Yemen into Saudi Arabia in 2017 were made in Iran and introduced into Yemen after the 2015 arms embargo. Tehran has denied sending weapons.
