NBC altered its programming lineup Friday evening in the wake of attacks that left more than 120 people dead and many more injured across Paris.

The network aired a rerun of the sitcom Undateable in the 8 p.m. ET time slot, rather than the live episode that was originally intended. Executive producer Bill Lawrence acknowledged the attacks on Twitter, writing “Goodnight. Be with your family.” He also posted a photo of the Undateable cast and crew holding up images of the Eiffel Tower as a peace sign.

NBC is airing original episodes of Truth Be Told and Grimm as planned at 8:30 p.m. and 9 p.m.

The 10 p.m. hour usually dedicated to Dateline will be used for live news coverage.
