PARIS, Nov. 13 (UPI) -- For the third time this year, Paris has become a target for deadly terrorist attacks.
While no group had claimed responsibility late Friday for shootings and explosions that killed more than 100 people at several locations around the famous city, officials believed it was an elaborately coordinated plan.
The massacre comes less than three months after a planned attack on a French commuter train on Aug. 21 that was foiled by two American servicemen and a friend who happened to be onboard.
Twenty-five-year-old Ayoub El-Khazzani of Morocco, who wielded an AK-47 on the train, was charged with terrorism in the case. Born in Tetouan, Morocco, El-Khazzani moved to Spain in 2007 and then to Belgium earlier this year. In February 2014, Spanish authorities had warned France that El-Khazzani was an Islamist extremist who could travel to France.
He was carrying 270 bullets and a bottle of gasoline on the train, which was carrying 500 passengers from Amsterdam to Paris, and had watched a militant Islamist video shortly before launching the attack attempt, French prosecutors said.
Four days later, French President Francois Hollande said of the incident, "It is further proof that we must prepare for other attacks, and therefore protect ourselves."
France had increased security in the wake of January shootings at on the Charlie Hebdo satirical magazine and a Jewish supermarket in Paris that killed 17. Al-Qaida in the Arabian Peninsula claimed responsibility for that attack.
Brothers Said and Cherif Kouachi, who launched the assault on the magazine, died in a standoff with police two days into a manhunt.
AQAP was responding to the magazine's publication of cartoons depicting the Prophet Mohammed, but in a video after the attack elocuted broader offenses:
"It is France that has shared all of America's crimes," the group's leader Anwar al-Awlaki -- who died in 2011 -- said in the video statement. "It is France that has committed crimes in Mali and the Islamic Maghreb. It is France that supports the annihilation of Muslims in Central Africa in the name of race cleansing."
With its population of more than 5 million Muslims, France has become a recruiting ground for violent Islamist networks, the Economist reported earlier this year, supplying more of its people to fight with jihadists in Iraq and Syria than any other European country.
The French government has strengthened counterterrorism laws and is working on a defense budget that would spend more to fight terrorism. In April, France dispatched 7,000 soldiers to protect sensitive locations.
