France carried out its first airstrikes against ISIS in Syria. The country had announced earlier this month that it would expand its aerial campaign against ISIS in Iraq, which it began a year ago, to include the militant group’s positions in Syria. The targets were based on intelligence gathered from air surveillance operations conducted over Syria during the past two weeks.

Six aircraft were used in the mission, which was led by the French but closely coordinated with the U.S.-led coalition. The target of the airstrikes was an Islamic State training camp, which was confirmed to have been destroyed. President Francois Hollande, speaking on the sidelines of the U.N. General Assembly in New York, described the camp as a “threat to our country.” “We reached our goal and the whole training camp was destroyed,” Hollande said.

Hollande told reporters the strikes on the training camp, and future strikes were aimed at “protecting our territory, cutting short terrorist actions, acting in legitimate defense.” He said more strikes could take place in the coming weeks if necessary. The targets were identified in earlier French reconnaissance flights and with information provided by the U.S.-led coalition. France has carried out 215 airstrikes against ISIS extremists in Iraq as part of the U.S.-led coalition since last year but it previously held back on engaging in Syria.

France has been the site of a number of terrorist attacks this year. Islamic extremists killed 17 people in a quick succession of attacks in Paris in January, including the shooting deaths of staff members in the offices of the satirical magazine Charlie Hebdo.

In June, authorities said a man in southeastern France killed his boss and displayed body parts with Islamist banners and also set off an explosion in a factory. Last month, three American men brought down a suspected terrorist gunman who tried to open fire on a train bound for France.

France has also linked the refugee crisis Europe is facing in part to ISIS, saying it would strike the group for driving thousands of civilians out of Syria.  French Prime Minister Manuel Valls told CNN, “We’re not going to receive 4 to 5 million Syrians, so the problem has to be dealt with at source.”
