LilithS, a Belgian activist group, poured gallons of fake blood on the lobby floor of Liège Airport in a dramatic ?Free Palestine? Protest on August 26. The demonstrators chanted pro-Palestinian slogans and unfurled a banner asking, ?How many tons of ******* for so many liters of blood?? In a statement on its Facebook page , the group alleges that US arms destined for Israel pass through the airport. Credit: YouTube/LilithsRevolt
