By ZEKE MILLER, FOSTER KLUG, JOSH BOAK, and ELAINE KURTENBACH (Associated Press) HIROSHIMA, Japan (AP) — President Joe Biden on Friday endorsed plans to train Ukrainian pilots on U.S.-made F-16 fighter jets, according to two people familiar with the matter, as he huddled with leaders of the world’s most powerful democracies on plans to toughen punishments on Russia for its 15-month invasion of Ukraine. The Group of Seven leaders were convening in Hiroshima, where President Volodymyr Zelenskyy is to join them on on Sunday in his farthest trip from his country since the war began in February of last year. The leaders heard for the first time of Biden’s backing of training Ukrainian pilots on advanced fighter jets, as a precursor to sending the jets to Ukraine. The G7 leaders also set out new sanctions on Moscow as well as plans to enhance the effectiveness of existing financial penalties meant to constrain President Vladimir Putin’s war effort. “Our support for Ukraine will not waver,” the G7 leaders said in a statement released after closed-door meetings.
