BAGHDAD, Iraq (CNN) -- Iraqi authorities have sent additional national police brigades to the border with Syria amid heightened tensions between the two nations, Ministry of Information officials said Saturday.
The move comes after Iraq demanded that Damascus turn over two Iraqis living in Syria who are believed to be part of last month's terror attacks in Baghdad.
Syria and Iraq each recalled their ambassadors from the other country last week after Iraqi authorities made the request.
The string of bombings struck Iraq's capital on August 19, with two truck bombs ripping through the Iraqi Finance Ministry and Foreign Ministry.
At least 100 people were killed and hundreds more were wounded in Baghdad's bloodiest day since U.S. troops handed over security control to Iraqi forces and moved outside of Iraqi cities nearly two months ago.
