The International Chamber of Shipping association said the "attacks must stop immediately, and the innocent seafarers released".
"In light of the threat to safe transit of global trade in the Arabian and Red Seas, ZIM is taking temporary proactive measures to ensure the safety of its crews, vessels, and customers' cargo by re-routing some of its vessels," ZIM said.
U.S. maritime administration MARAD said in an advisory on Sunday that vessels faced multiple threats after the attacks.
Insurance industry sources said they expected war risk premiums to rise in the area, especially for Israel-linked shipping.
