Baghdad: Iraqi troops have raided Baghdad’s Shiite districts and found large caches of weapons, including helicopter missiles and an anti-aircraft gun, the US military said on Saturday.

The statement said government forces had seized 100 caches of weapons, including 295 mortar rounds, 367 AK-47s, 109 anti-tank mines, 39 rocket-propelled grenade launchers.

Troops also found an anti-aircraft gun, six helicopter rockets, sniper rifles, improvised explosive devices, 123 grenades and artillery shells.

The military said the weapons seized in the last three weeks gave the first real glimpse of the formidable arsenal that the Mehdi Army militia has been building up.
