Zelenskyy: 'This week alone, the Russians used over 1,900 attack drones, 1,700 aerial bombs, and 25 missiles against Ukraine. More than 800 of the drones were jet-powered, and Russia must be held accountable for this escalation. Friedrich Merz, the Federal Chancellor of Germany, is visiting Kyiv today. Germany is a country that consistently demonstrates leadership in protecting Ukrainian lives from Russian strikes. '
