France says it's at war and its young people are heeding the call of duty.

The number of daily applications received by France's armed forces has tripled since the Nov. 13 terrorist attacks in the Paris area, which claimed 130 lives and injured more than 300 people. People signing up to join the military went up to about 1,500 from an average of 500, a spokeswoman for the French army said by phone. France's army has said it needs to fill 15,000 positions in 2015 and 16,000 in 2016.

"What happened last Friday really convinced me that was what I wanted to do; I felt so powerless watching TV," said Hamilton Mithun, 19, who was at the Fort Vincennes military recruitment in eastern Paris on Friday. "I wanted to be helpful. That's why I am here."
