Iraqi Prime Minister Haidar al-Abadi said on Wednesday the fighting in Yemen could engulf the region in war, and suggested after talks in Washington that U.S. leaders shared his concerns and "want to stop this conflict as soon as possible."

Abadi, who met with U.S. President Barack Obama on Tuesday, also said that convincing Iraq's neighbor, Saudi Arabia, to halt its offensive in Yemen could be difficult.

Saudi Arabia is engaged in a three-week-old campaign of airstrikes against Yemen's Houthi rebels, who are allied with Iran and have taken over the capital and forced the president to take refuge in Riyadh.
