Terrorist attacks throughout Paris Friday night have killed more than 100 people, prompting France to declare a state of emergency and to close its borders. Caught in the middle of the violence are thousands of Airbnb hosts and employees attending the company's annul Airbnb Open conference. 

The conference, which was expected to draw 6,000 hosts and was scheduled to end Nov. 14, has never been held outside San Francisco before. Paris has emerged as the top destination for Airbnb stays, counting 40,000 listings.

Airbnb CEO Brian Chesky announced on Twitter Friday that the final day of the conference is canceled in response to the violence in the city.

French President Francois Hollande, who has been evacuated, has called the terrorist attacks "horrific" and said they were "of an unprecedented scale."

Some Airbnb employees and others attending the conference witnessed the aftermath of shootings. Shootings took place in at least two restaurants, there was an explosion at a sports stadium assumed to be a suicide bombing, and hostages were taken at a concert hall.

The conference hotel is located between the stadium and the concert hall, placing attendees and San Francisco-based staff in a dangerous position.

Inc. has contacted Airbnb and conference attendees and will update if anyone responds.

Here are some of the reports on Twitter so far from attendees:
