Former President Donald Trump expressed his condolences after Thursday's twin bombings at the airport in Kabul that killed 12 U.S. service members. "Melania and I send our deepest condolences to the families of our brilliant and brave Service Members whose duty to the U.S.A. meant so much to them," Trump wrote in a statement. "Our thoughts are also with the families of the innocent civilians who died today in the savage Kabul attack." "This tragedy should never have been allowed to happen, which makes our grief even deeper and more difficult to understand," he continued.
