Within the last quarter of an hour, word is filtering out (via Twistter) that the convoy is turning about and heading back to Iran.

Iranian convoy believed to be carrying weapons destined for Houthi rebels in Yemen have turned back toward Iran. -@JimMiklaszewski
Probably best to check back in a few hours, but perhaps things have been defused for the time being.
