(Portland, OR) -- New details are coming to light regarding the arsons that damaged hundreds of ballots at three ballot dropboxes in the Portland and Vancouver areas this week. ABC News and the New York Times are reporting the incendiary devices used to attack the ballot boxes on Monday all had the phrases, "Free Gaza" or "Free Palestine" written on them. It remains unclear whether the bombs were planted by an actual pro-Palestinian activist or if the suspect used the phrasing to try to play on existing divisions in the U.S. Police say one ballot box in Portland and two in the Vancouver area were targeted. Police believe a person in a Volvo that's seen on camera pulling up to one of the ballot boxes is responsible for setting them on fire.
