Shots have been fired at the motorcade of Pakistani Prime Minister Yousuf Raza Gilani, although it is not clear if he was in the convoy at the time.
Two bullets from an unidentified gunman hit the PM's car as he was travelling from Islamabad airport into the city, his press secretary told the BBC.
But security officials say the car was on its way to collect Mr Gilani.
Mr Gilani's government is grappling with a growing threat from militants in the country.
The BBC's Barbara Plett in Islamabad says it is not clear who fired the shots but Islamist militants based in Pakistan's border regions have threatened to kill various government ministers, and have carried out deadly suicide bombings against army and government targets.
The incident represents a major lapse in security. In December former Prime Minister Benazir Bhutto was killed at an election rally in Rawalpindi.

"I can confirm the prime minister's convoy was fired upon while returning from [Islamabad] airport," his press secretary Zahid Bashir told the BBC.
