A two-year probe into the Madrid train bombings concludes the Islamic terrorists who carried out the blasts were homegrown radicals acting on their own rather than at the behest of Osama bin Laden’s al-Qaida network, two senior intelligence officials said.

SPANISH police yesterday arrested a north African man who is suspected of involvement in the train bombings that killed almost 200 people in Madrid last month.

At least five prime suspects in the Madrid bombings were among the seven alleged terrorists who blew themselves up as police moved to arrest them earlier this month, officials said today.
