Nearly 40 people have been killed in fighting outside Yemen's Hudaydah port, medical sources say.
It comes on the second day of a major offensive by a Saudi-led coalition that includes troops from the United Arab Emirates and pro-government forces.

Barbara Leaf is the former US ambassador to the United Arab Emirates - she calls it an "inflection point".
