Artists4Ceasefire, the industry collective that has been pushing for an end to the current war in Gaza (and whose pin badges were worn by various attendees at this year’s Oscars ceremony), is spearheading a new initiative calling for a halt to illegal arms sales to Israel.

Through a partnership with artist Shepard Fairey and several humanitarian organizations — including Oxfam America, ActionAid USA and War Child Alliance/Children in Conflict — the group has launched a call to action bearing the message “Ceasefire Now, Stop Weapons, Save Lives” that urges the halt to what it says are “weapons transfers that violate U.S. and international law.” Such laws state it is illegal to supply or use weapons to commit “grave human rights violations,” including striking schools or hospitals, restricting humanitarian aid, and killing children.
