Iran's parliament (Majlis) summoned Pakistan's ambassador to Tehran over a kidnap issue, the local Press TV website reported on Tuesday.
Tehran summoned the ambassador Muhammad Bakhsh Abbasi "to pursue the case of a kidnapped Iranian diplomat seized by gunmen last year," the report said.
Head of the Iranian Parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi said Tuesday that it was a protest to the uncertain fate of the kidnapped Iranian diplomat Hashmatullah Attarzadeh, Xinhua reported.
"The case of Attarzadeh's kidnapping has been long drawn-out. Majlis summoned the Pakistani ambassador to convey concern about the fate of the kidnapped diplomat," Boroujerdi was quoted by Press TV as saying.
The diplomat was kidnapped and his Pakistani guard was killed after a November shoot-out in Peshawar in northwestern Pakistan.
An Iranian Sunni rebel group based in southeastern Iran, the Jundullah (Soldiers of God), has constantly been blamed for offense and kidnappings in southeastern Iran at the border zone with Pakistan.
The group, which is the target of Iran's border police operation, killed 16 policemen it kidnapped in southeast Iran in June.
