DUBAI (Reuters) - Saudi Arabia is seeking Washington's help in bolstering its defences as it comes under intense U.S. pressure to end a blockade of Yemeni ports that its Houthi enemies say is an obstacle to ceasefire talks, two sources with knowledge of efforts to end the Yemen war and a U.S. official said.
A Saudi-led military coalition intervened in Yemen in 2015 after Houthi forces ousted the internationally recognised government from the capital, Sanaa.
