I have no way of verifying it, but that’s what Omar at Iraq The Model is saying. Money quote from a report in an Iraqi paper:
The Iraqi daily az-Zaman which is published in London and Baghdad quoted credible Iraqi sources as revealing that the IRGC had given al-Qaeda in Iraq, Strela-type SAM-7 surface-to-air missiles, modern explosives, and a large number of personnel arms including Kalashnikovs and BKC machineguns.
Al-Qaeda in Iraq is believed to be led by Abu Musab al-Zarqawi, who is on the United States’ wanted list.
The report said that representatives of al-Zarqawi’s group met in Beirut with members of the Iran-backed Lebanese group Hezbollah and through them established channels with Tehran.
Three close aides to al-Zarqawi travelled to Iran via a security checkpoint in the Iraqi border province of al-Amara from where they met with Iranian officials, the report added.
Why Iran would funnel support to people who target Iranian-allied Shiites is beyond me. Unless, perhaps, they fear that the Jihadist insurgency is fading, and that the new Maliki-led government has a chance at gaining legitimacy and support, while including Sunni Arabs. I don’t know, but this report surely deserves further inquiry from other media sources.
