Double-bombing wounds 3 police in Iran Iranian police say a double-bombing has lightly wounded three police in the southeastern city of Zahedan

TEHRAN, Iran -- Iranian police say a double-bombing has lightly wounded three police 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.

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 police and wounding 42 other people.
