Angry student protesters clashed with police Sunday in Paris as far-right National Front Party candidate Marine Le Pen was projected to advance from the first round of France's presidential election, according to reports.

Crowds angry with Le Pen’s advancement gathered on Place de la Bastille to protest. As they became rowdier, police lobbed tear gas into the crowd to try to disperse them, according to the Telegraph.

Center-left candidate Emmanuel Macron and Le Pen are expected to go head-to-head in a runoff election on May 7.

Le Pen beat out François Fillon, a conservative contender, who called on his supporters to vote for Macron instead of Le Pen.

With about 34 percent of the vote counted at 9:30 p.m. local time, France's Interior Ministry found Le Pen leading with 24.6 percent of the vote followed by centrist Macron with 21.9 percent, according to the Associated Press.

Le Pen has claimed victory, the AP said, and promised the National Front party would represent "the great alternative" to the French people. French President François Hollande reportedly congratulated Macron on reaching the runoff.

Le Pen campaigned on staunch, hardline anti-immigration stance, and she has also advocated for stepping back France’s commitment to the NATO alliance.

Some say that if Le Pen won the election, she could spur a controversial referendum in France to leave the European Union similar to Brexit — a “Frexit.”

Protesters who oppose her anti-immigration views and political stances also demonstrated at some of her campaign events.
