The weekend saw an exchange of accusations between the U.S. and Israel over Israel's airstrike in northern Syria earlier in the week. Israel stands by its claim that the strike against the Abu al-Duhur airbase in Syria was meant to foil the transfer of war materiel and the placement of Turkish military advisers at the base before the attack. U.S. diplomat Tom Barrack, President Donald Trump's envoy to Syria and the American ambassador in Turkey, criticized the attack and hinted that it was carried out for political purposes. Trump himself has not yet spoken about this issue.
