Belgian Prime Minister Charles Michel said the country's capital, which also houses the headquarters of the European Union and NATO, faced a "serious and imminent" threat of attack.

France deployed more than 100 riot police to Calais on Wednesday to bolster security as hundreds of migrants have been trying night after night to rush the railway tunnel leading to England — at times with fatal consequences.

With explosions and gunfire, security forces Friday ended three days of terror around Paris, killing the two al-Qaida-linked brothers who staged a murderous rampage at a satirical newspaper and an accomplice who seized hostages at a kosher supermarket to try to help the brothers escape.

One man sought in the deadly shooting at a French satirical paper has turned himself in, and police hunted Thursday for two heavily armed men with possible links to al-Qaida in the military-style, methodical killing of 12 people.
