Warplanes from the Saudi-led coalition hit Yemen rebel positions in the central city of Taez early Saturday, shortly after a UN humanitarian truce came into effect, witnesses said.

Two air raids targeted Shiite Huthi rebel positions in Arbaeen Street in Taez, where clashes between the Iran-backed insurgents and fighters loyal to exiled President Abedrabbo Mansour Hadi continued after the truce began at midnight, witnesses said.
