Cease-fire deal in sight, Iran says

Ships believed to be on way to drop off supplies for Houthi rebels as Saudi airstrikes continue

A US aircraft carrier was headed to the Arabian Sea on Tuesday as Washington said it was monitoring Iranian vessels suspected of carrying weapons to Houthi rebels in Yemen in violation of a UN embargo.

The US said it was sending the USS Theodore Roosevelt and guided-missile cruiser USS Normandy "to ensure the vital shipping lanes in the region remain open and safe".
