The United States provided an anti-Iran terrorist group with the bomb used to assassinate Iranian scientist Mostafa Ahmadi Roshan last month, a report has revealed. Two bombs were handed over to the Party for Free Life of Kurdistan (PJAK) in the Iraqi city of Arbil by the Americans, the Resalat daily reported on Monday. The first bomb killed Ahmadi Roshan, but the second one was discovered by intelligence and security personnel around Resalat Square in the capital Tehran, the report said.
