Serbia's President Boris Tadic has survived an apparent assassination attempt when a car tried to crash into his motorcade in Belgrade.
Pro-Western Boris Tadic survived the attack on Tuesday night
Mr Tadic was not hurt in the incident when the driver of an Audi repeatedly tried to hit his car, a spokesman said.
He said security officials in another car in the motorcade prevented a crash by blocking the attacker's vehicle. The black Audi fled the scene.
In 2003, pro-western Prime Minister Zoran Djindjic was killed in Belgrade.
Mr Tadic, also a pro-western politician, was sworn in as the new president in July this year after an 18-month spell during which the post was left vacant.
His car was travelling through Belgrade's plush Dedinje district at around 2100 local time (2000GMT) on Tuesday when it was attacked, the spokesman said.
One of the vehicles in Mr Tadic's convoy was damaged, the spokesman added, although the president's car was not hit.
Mr Tadic's office said that security officers believed the Audi had followed the convoy for some time before trying to attack the president's car.
Belgrade daily newspaper Vecernje Novosti claimed the attacker tried to cut the convoy off and run into the presidential vehicle on a curve.
The driver of the Audi attempted to avoid Mr Tadic's security vehicle but the escort vehicle veered sharply left and crashed into the attacker, the newspaper said, quoting "well-informed sources".
It added that officials noted the first two digits of the Audi's licence plate, and have passed the details onto police.
Another daily, Blic, reported that the driver had a beard.
Mr Tadic is widely resented by Serbian nationalists for his pro-Western policies and staunch support for the UN war crimes tribunal at The Hague.
He has called for the extradition of a host of war crimes suspects to face the tribunal, where former Yugoslav President Slobodan Milosevic is currently on trial.
Thirteen men accused of conspiring to assassinate Mr Tadic's predecessor, Zoran Djindjic, are on trial in Serbia for the murder.
