Donald Trump disparaged the Russian military and backed Ukraine to retake all its occupied territory in an astonishing about-turn on the war. Mr Zelenskyy told Sky News US correspondent Mark Stone it was a "big shift" from his US counterpart. Just last month, Mr Trump rolled out the red carpet for the Russian president at a summit in Alaska - in a push to expedite the war's conclusion. He said Mr Trump had "worked on it tirelessly", but warned Russia his patience is not "infinite". Last week, Estonia said three Russian MiG-31 fighter jets violated its airspace for 12 minutes before Italian NATO jets escorted them away.
