Spain: Model plane video evidence of terror plot

Spanish officials allege the suspects were planning a terrorist attack in Spain or elsewhere in Europe, but say investigators managed to intercept them before they could carry out their plot.

The undated video clip - grainy and of low quality - shows a colorful model propeller plane noisily taking off. Once airborne, it drops a small object that falls to the ground and a man then runs toward where the object landed. The identity of the man is not clear from the clip.

Two of the arrested suspects are Russians of Chechen descent — Eldar Magomedov and Mohamed Ankari Adamov. They were jailed Sunday on provisional charges of belonging to a terrorist organization.

The third man, a Turk named Cengiz Yalcin, was also jailed on provisional charges of possession of explosives and a device likely to be used in a terror attack.

Spain's Interior Ministry also released photographs of an underground space uncovered by police at Yalcin's home in the southwestern city of La Linea where investigators discovered around 150 grams (5.3 ounces) of an allegedly explosive substance.
