President Bush has left the White House for a five-day trip to Ireland and Turkey, seeking to build an international consensus on Iraq.
Mr. Bush departed Friday, to attend a summit with European Union leaders in Ireland on Saturday and a NATO summit in Turkey that begins on Monday.
In an interview with Turkish television broadcast Friday, Mr. Bush said it is not likely that NATO countries will contribute additional troops to Iraq. But he said he is hopeful some countries will help train Iraqi forces.
U.S. Secretary of State Colin Powell is accompanying Mr. Bush on the trip.
Thousands of Irish police officers and soldiers have deployed around Dromoland Castle, the site of Saturday's EU summit, in anticipation of protests there.
