"We don't want to send booby-trapped cars for the ones that are sent to us. We are capable of that but this is not the nature of the new Iraq," national security advisor Muwafaq al-Rubaie told reporters in neighbouring Kuwait.

"Neighbours are sending death vehicles, terrorists, financial and logistical support and also plotting," the Shia politician said, declining to point the finger at any particular country.

"We will give them more time to reconsider their calculations ... We don't want to open fire on any country ... but Iraq's patience has a limit," he added on the sidelines of an Iraq donors' conference.

A senior official from a neighbouring country will visit Iraq in the next few weeks to discuss a political solution, Rubaie added without elaborating.

Deputy Prime Minister Barham Saleh, a Kurdish politician, later pointed the finger at Syria and called on it to do more to stop the infiltration of "terrorists" across the border.

Meanwhile, more than 40 Shias were abducted along a notoriously dangerous highway just north of Baghdad, police said yesterday, and the death toll from a suicide bombing at a wedding party rose to 23, including nine children.

At least eight other people were either found dead or slain in new attacks Wednesday, including one person killed in a car bomb attack in Baghdad's central market, which wounded five others, police Lt. Ali Hassan said. The death toll in the market attack was likely to rise, he said.
