Iranian police say a double-bombing has lightly wounded three police officers in the southeastern city of Zahedan.

 

Gen. Mohammad Ghanbari, the provincial police chief, told the official IRNA news agency that the second bomb went off as police raced to the scene of the first explosion. He says the bombs were handmade and that police are investigating.

 

Some Iranian officials said the explosions were caused by percussion grenades.

 

An earlier report by the news website of the Young Journalists Club, which is linked to Iran's official radio and television station, said two suicide bombers blew themselves up in front of a police station.

 

Zahedan is the capital of Sistan-Baluchistan province, which has seen past attacks by Baluch separatists and drug traffickers.

 

Last month a suicide car bomber struck a police headquarters in the port city of Chabahar, also in Sistan - Baluchistan, killing at least two policemen and wounding 42 other people.
