Iraqi Prime Minister Nouri al-Maliki has cast doubt on receiving any support from neighboring Syria to end terrorism in the region, Press TV reported.
In a statement released on Tuesday, Maliki called for the establishment of an independent UN commission to look into the August 19 bombings of its finance and foreign ministries after Syria's failure to respond to his request for handing over of a list of terror suspects said to be hiding in Syria.
"We have almost no hope that these efforts will succeed," the statement notes.
The Prime minister had earlier charged that 90 percent of foreign fighters who enter Iraq come through Syria -- including terrorists accused of carrying out August attacks.
"From the beginning, we did not expect to receive a response from Syria to the Iraqi demands," said the premier.
Syria had formerly signaled that it will be open to Turkish mediated efforts to settle the recent row between the two neighbors.
Maliki however rejected requests from Arab neighbors for Iraq's acceptance of a negotiated way out of the diplomatic crisis.
He insisted he would continue to press for a UN probe into the attacks, which killed almost 100 people and wounded at least 600 others in Baghdad.
The attacks led to a row that saw Baghdad and Damascus recalling their envoys six days after the bombings.
