Police probe attack on PM's motorcade

ISLAMABAD (Agencies) - Police searched for clues Thursday as to who carried out a failed assassination attempt on Prime Minister Yousuf Raza Gilani, a day after sniper fire struck his motorcade.

The premier was not in the targeted vehicle at the time, but the brazen daytime attack on Wednesday underscored security fears in the world's only nuclear-armed Islamic nation ahead of Saturday's presidential election.

Interior advisor Rehman Malik said investigations were underway but declined to give any details. "We hope the investigations will be finalised in two or three days," he said.

Security officials told AFP that police were examining the site on the main highway to the airport and that the government was awaiting a ballistics report.

Sniffer dogs were taken round the area but officials said no clues were found.
