French Arrests Show Europe's Growing Struggle to Contain Terror Threat

Four suspects have been arrested in the Paris region amid fears they were planning another terror attack.

Few details have been made available, but French Interior Minister Bernard Cazeneuve says, alarmingly, that French authorities now have to make arrests like these every day.

Tensions are high in France following the November terror attacks in Paris that left 130 people dead. Security forces killed one suspect during a terrorist raid in Brussels Tuesday, but two others escaped and are on the run.

"One suspect was neutralized by a sniper of the Special Forces when he tried to open fire toward the police from a window of the flat where he was hiding," said Eric Van Der Spyt, spokesman for Belgium's federal prosecutor.

The European Union's crime-fighting union says the Islamic State has set up a special operations command to launch terror attacks on soft targets in Europe using training camps on European soil.

Belgium and France have become home to some of Europe's most dangerous terrorists and police have their hands full, to say the least.
