Baghdad  - Iran has bombed Kurdish rebel positions in villages along the Iraq-Iran border on Thursday, a senior Iraqi official has said.

"Heavy shelling began at midnight and continued for an hour," the director of Sulaymanyah Zarawa district, Ezad Wasso, told the Voices of Iraq (VOI) news agency.

The bombing targeted the areas of Razka, Mardo, Shanawa, and Arka, some 15 kilometres from the Iraq-Iran border, Wasso explained, adding that no casualties were reported.

The Iranian attack was targeting the Party of Free Life of Kurdistan (PJAK). PJAK is a militant Kurdish group based in northern Iraq. The group has been attacking the Kurdish province of Iran and other Kurdish areas. (dpa)
