Iran is to reopen its border to Iraq's Kurdistan, the ISNA news agency reported Saturday. An unnamed Iranian security official told ISNA that following a visit of an Iraqi Kurdish delegation to Iran, Tehran agreed to reopen its border to northern Iraq as of Sunday. Senior leaders from the Patriotic Union of Kurdistan (PUK) and the Kurdistan Democratic Party (KDP) had come to Iran on Thursday to settle the dispute triggered by the US forces' arrest of Iranian citizen Mahmoud Farhadi in Suleimaniya, reported DPA. Farhadi is suspected by the US of being involved with Iran's Islamic Revolutionary Guard Corps-Quds Force and of allegedly smuggling weapons into Iraq but Tehran said he was officially invited by the Iraqi Kurds for trade talks, DPA said.
