MADRID, Spain (AP) - Police found a bomb Friday under the track of Spain's bullet train line between Madrid and Seville, the Spanish interior minister said. Bomb-disposal experts alerted by a railway employee found 22-24 pounds of explosive that might be dynamite about 40 miles south of Madrid, Interior Minister Angel Acebes said.
The explosives were connected to a detonator with a 450-foot cable, the minister told a news conference.
The track is used by Spain's Ave trains, which can reach speeds of 186 mph.
Acebes said it was not known who placed the bomb.
The bomb's discovery came less than a month after 10 backpack bombs ripped through four commuter trains in Madrid, killing 191 people and injuring more than 1,800. The focus of the investigation is a Moroccan extremist group with links to al-Qaida. The bombs were detonated with cell phones attached to the explosives.
On Thursday, police in northern Spain defused three letter bombs addressed to journalists in Madrid.
Acebes said the origin of the letter bombs has not been determined, although the mechanism of the bombs is "similar to those that have been used by anarchist groups on previous occasions."
