TOULOUSE, France (AP) -- French President Nicolas Sarkozy says authorities are raising the terrorism alert to its highest level across a swath of southern France where a gunman opened fire on a Jewish school before fleeing.
Sarkozy said Monday's attack in Toulouse, which killed three children and a rabbi, was the worst-ever school shooting in France. One of the weapons used Monday was the same used to kill three paratroopers in two different attacks in the Toulouse region last week.
Sarkozy suggested one person was behind all three attacks.
He said the terror alert level is being raised to scarlet, the highest on a four-point scale, in the region that includes Toulouse and neighboring areas.
Sarkozy said 14 riot police units "will secure the region as long as this criminal" hasn't been caught.
