Syria and Iraq have re-opened embassies in each other's capitals for the first time in more than two decades.
They agreed last month to resume diplomatic relations that were severed because of Syria's support for Iran during the Iran-Iraq war in the 1980s.
Meanwhile, in violence Monday, bombings killed two people in Baghdad. And gunmen wearing Iraqi army uniforms stole one million dollars and kidnapped four security guards from a vehicle transporting the money to the central bank in Baghdad.
In western Baghdad, U.S. and Iraqi troops found and freed 23 kidnapped Iraqis and arrested six men suspected of abducting them.
The U.S. military also says a Marine helicopter made an emergency landing in Anbar province, injuring 18 people on board.
But officials do not believe the helicopter was forced to land because of enemy action.
Roadside bombs killed four American soldiers in Baghdad on Sunday.
