A U.N. team overseeing the truce in the Yemeni port of Hodeida came under fire Thursday.
No one was injured when bullets struck an armored vehicle carrying chief monitor Patrick Cammaert.
The Yemeni government and Houthi rebels blamed each other for the shooting.
U.N. spokesman Stephane Dujarric said both sides needed to make sure everyone with the U.N. was safe.
