Eight people at an outdoor mall in Boulder, Colo., calling for the release of Israeli hostages in Gaza were injured on Sunday by a man police say attacked a crowd with makeshift incendiary devices and a flamethrower.

One victim from Sunday's terror attack in Boulder, Colorado, is a survivor of the Holocaust, according to a government official.

In the wake of the June 1 attack on a pro-Israel demonstration, community members and officials condemned the act and offered support to the community.
