Saudi Arabia has resumed airstrikes against Shiite Houthi rebels in Yemen, hours after announcing an end to its nearly month-long bombing campaign. The Saudi Defense Ministry said it would conclude the airstrikes and shift to a new strategy focused on a political solution. But after rebels gained ground in the central city of Taiz, the strikes resumed. Meanwhile on Tuesday, two airstrikes killed at least 40 people, most of them civilians. On Monday, the Committee to Protect Journalists reported a TV journalist and three staff members of the TV station Yemen Today were killed in an airstrike in the capital Sana’a.
