PARIS (AP) — French fighter jets launched their biggest raids in Syria to date, targeting an ISIS stronghold in Raqqa just two days after the group claimed coordinated attacks in Paris that killed about 130 people.  The raid involved 12 aircraft, including 10 fighter jets, and was launched simultaneously from the United Arab Emirates and Jordan

A hunt for a suspect in the Paris attacks focused today on a Brussels neighborhood where two small explosions were heard as dozens of masked and heavily armed security officials sealed off the area. The first explosion happened about two hours into the siege followed by a similar blast one hour later on a higher floor of a building with special security forces close by on roofs. Police gave no details. France has identified a Belgian as the suspected mastermind of the Paris attacks and also linked him to thwarted train and church attacks.

French Interior Minister Bernard Cazeneuve says scores of overnight raids across France are “just a start” to France’s response to the Paris attacks. He says there were 168 raids and 104 people were placed under house arrest in the past 48 hours. Cazeneuve says “the response of the Republic will be huge, will be total.”

Simultaneous moments of silence were observed today in Paris and at the G-20 summit in Turkey for the 129 victims of the Paris attacks. Standing between the French and the European Union flags at the G-20, leaders stood in silence at the same time as French President Francois Hollande (frahn-SWAH’ oh-LAWND’) observed a minute of silence along with schoolchildren and bystanders in Paris. Black ribbons were tied around the French and EU flags in a sign of mourning.
