AIR strikes by the United States pummelled sites across Houthi-controlled Yemen today, including targets in the capital Sanaa.

The extent of the damage and number of casualties wasn’t immediately clear, though the bombing was reported as particularly intense compared to other days in the campaign, which began on March 15.

Initial reports from the Yemeni authorities described at least seven people being hurt in the attacks in Sanaa, which the rebels have held since 2014.
