WASHINGTON: US envoy Steve Witkoff, President Donald Trump’s chief negotiator on the Middle East, has said that he felt “betrayed” when Israel launched a strike targeting Hamas negotiators in Qatar last month. In a CBS interview alongside Jared Kushner, Trump’s son-in-law who worked with Witkoff on the brokering of a Gaza ceasefire deal between Israel and Hamas, the presidential envoy said he learned of the September 9 attack in Doha the morning after it happened. Qatar is a key US ally and acted as mediator in the push to end the Gaza war.
