Morocco ? Acting on a tip, Moroccan police surrounded a building where four terrorism suspects were holed up Tuesday, causing three to flee and blow themselves up with explosives. The fourth was shot dead by a police sharpshooter as he apparently tried to detonate his bomb.

A police officer was killed and 10 people, including a young child and a policeman, suffered injuries.

Coming just weeks after a bombing at an Internet cafe, the series of explosions revived memories of five near-simultaneous suicide bombings that killed 45 people in the country’s biggest city in May 2003 – this North African kingdom’s first brush with Islamic terrorism.

Police have since pursued an unprecedented crackdown on suspected militants, arresting thousands of people, including some accused of working with al-Qaida and its affiliates to plot attacks in Morocco and abroad.
