The G7 has vowed to continue military aid for Ukraine and expand sanctions on Russia. This was included in a joint statement by the group's foreign ministers as they met in Germany on Saturday. Meanwhile, Moscow says it will respond with adequate precautionary measures if NATO deploys nuclear forces and infrastructure closer to Russia's border. On the ground, Kyiv says its troops are pushing back Russian forces north of the city of Kharkiv, and are reclaiming more villages.
