A Maersk cargo ship
Maersk is shutting down travel through the Red Sea again after a Houthi rebel attack.
  • An Iranian warship entered the Red Sea a day after US Navy took out three Houthi attack boats.
  • Iran-backed Houthi attacks in the Red Sea continue to threaten global commerce.
  • Maersk again paused shipping through the Red Sea in response to recent attacks.

An Iranian warship sailed into the Red Sea Monday, according to Iranian state media and other reports, risking a potential escalation of tensions in waters where attacks on commercial shipping are becoming frequent and forcing navies to intervene.
