Bub and Pop’s will be closed this week following the death of a family member. Staff Sargent Peter Taub—brother and son to owners Jonathan Taub and Arlene Wagner—was killed yesterday in Afghanistan.

The sandwich shop’s owners shared in a Facebook post that Taub was one of six Americans killed in Afghanistan yesterday. The New York Times reports a Taliban suicide bomber drove a motorcycle into a military convoy—one of the deadliest attacks against U.S. troops in Afghanistan this year.
