Shiraz mosque blast

TEHRAN, May 17--Iran's Intelligence Ministry said on Saturday US agents had armed and trained those behind a deadly blast in a mosque last month and that pipelines in the country's oil-rich south were also among the planned targets.

Washington and London have been blamed by Tehran of trying to destabilize Iran by supporting rebels, mainly those in sensitive border areas.

Intelligence Minister Gholamhossein Mohseni-Ejei had said 15 people had been arrested in connection with the blast and they had also plotted to attack a Russian consulate in northern Iran.
