Ariane Theiller, an intern for French publisher Urban Comics, was among the victims killed in Friday's terrorist attacks in Paris, the publisher has confirmed. Theiller was in attendance at the concert at the Bataclan theater where gunmen left 89 people dead as part of a series of coordinated attacks on the city.

Theiller was a master's student at the University of Strasbourg, and her internship at Urban Comics was part of her program. In a personal statement, she wrote of her internship and her interest in publishing, specifically for younger readers and in the comics medium.

Several comics professionals expressed condolences over Theiller's passing on social media:

No words to express the sadness of the loss of Ariane Theiller last night in Paris. My heartfelt sympathies to my friends at Urban comics.- Ivan Brandon (@IvanBrandon) November 15, 2015

On Facebook, writer Jason Aaron expressed his sympathies, and wrote that Urban Comics is "as much like a tight-knight little family as they are a publishing house."

Urban Comics publishes French translations of DC Comics releases and creator-owned comics including "Wytches," "The Sixth Gun" and "Southern Bastards." The publisher acknowledged Theiller's death on Facebook, writing, "We are all in shock."

Theiller's brother posted to Twitter on Friday night that his sister was among the unaccounted for in attendance at the Bataclan, in a post that was retweeted more than 7,000 times. Earlier today, he reported that she was among those who died in the attack.

At least 129 are dead in the terrorist attacks on Paris, which consisted of seven separate attacks, including three bombings and six mass shootings. The shootings at the Bataclan theater, which occurred during a concert by the American band Eagles of Death Metal, was the deadliest of the attacks. The following day, the Islamic State of Iraq and the Levant (also known as ISIL or ISIS) claimed responsibility for the attacks.

CBR extends its deepest condolences to the friends and family of Theiller, and all the victims of Friday's tragic and senseless attacks.
