A shooter opened fire Thursday in Paris' Champs-Elysees shopping district, wounding two police officers and killing a third. The assailant was then shot and killed by police. The Islamic State claimed responsibility for the attack via its Amaq news agency about two hours after the shooting was first reported. French officials said the suspect was previously known to authorities as an extremist. French police arrested two men earlier this week for allegedly planning a terrorist attack. The first round of France's presidential election begins on Sunday.
