MADRID ? �Spain's Interior Ministry has released a video that it says shows alleged al-Qaida suspects training for a bombing raid using a model plane and explosives.

The grainy and bad quality undated video clip released Saturday shows a colorful model propeller plane taking off. Once airborne it drops a small object that falls to the ground and a man then runs toward where the object hit the ground.

Spanish authorities have arrested three men on suspicions that they were planning a terrorist attack in Spain or elsewhere in Europe. Two are Russians of Chechen descent identified as Eldar Magomedov and Mohamed Ankari Adamov; they were jailed Sunday on provisional charges of belonging to a terrorist organization.

A Turk, Cengiz Yalcin, is suspected of possession of explosives.
