The Insider: Daily Terrorism Report

June 8 -- Police in Milan arrested Rabei Osman Sayed Ahmed on Tuesday, known as ``Mohamed the Egyptian,'' and another man as part of cross-border raids into the March 11 bombings that killed 191 people in the Spanish capital, news wires report. Mohamed the Egyptian, whom Spanish officials say allegedly "masterminded" the attacks, was staying in an apartment in the Bovisasca district on the northern outskirts of Milan, guest of another Islamic man who was also arrested. Aside from these detentions, Milan police have also searched 5 other apartments around Milan. The Italian Interior Minister Giuseppe Pisanu said militants had been planning more attacks as police swooped as part of an operation across Europe.

And an American was gunned down on Tuesday in Riyadh, Saudi Arabia's capital. The American worked for a U.S. contracting company, according to U.S. officials. His assailants have not been captured. The attack was the second this week against Westerners in Saudi Arabia. Sunday, Irish cameraman Simon Cumbers, 36, was killed and BBC security correspondent Frank Gardner, 42 was critically wounded in Riyadh. The violence has elevated security fears among the many expatriates living in Saudi Arabia.
