AMSTERDAM: A man with a Palestinian flag yelling ?God is great? was detained by police in the Netherlands on Thursday after smashing the windows of a kosher Jewish restaurant in Amsterdam. The violent outburst came a day after US President Donald Trump recognised Jerusalem as the capital of Israel, a decision that reversed decades of US foreign policy, angered much of the Muslim world and was widely rejected by Western leaders. The assailant, who was wearing a black-and-white-checkered head scarf, smashed several windows of the restaurant HaCarmel before he was pushed to the ground and hand-cuffed by police, a video of the incident posted on local media websites showed. ?We are disgusted,? the Organization of Jewish Communities in The Netherlands said in a statement. The attack was ?an act of revenge, meant to instil fear, and is no less than an act of terror.?
