Five crew members have been rescued from a Liberian-flagged cargo ship in the Red Sea after a suspected attack from Yemen’s Houthi group, according to a maritime monitor. The attack is so far known to have killed at least three sailors out of the 22-member crew and wounded two.

Another Greek-owned cargo ship was attacked in the Red Sea on Monday, resulting in at least two crew members wounded and another two missing.

The Houthis resumed targeting Red Sea shipping with two attacks on commercial vessels that killed three crew members and injured two more. The Yemeni terrorist group had not targeted commercial shipping in over half a year.
