US president said he is ready to impose further sanctions on Russia, but only if all NATO countries stop buying Russian oil, a huge source of income for Putin.

President Donald Trump demanded NATO and the rest of the world follow his lead when it comes to handling Russia, penning a “letter” to the world in an early Saturday morning Truth Social post threatening Moscow with “major” sanctions.

President Trump says he believes Russia's war against Ukraine would end if all NATO countries stopped buying oil from Russia and placed tariffs on China of 50% to 100% for its purchases of Russian petroleum.

Poland, a NATO ally, shot down some of the drones that violated its airspace and accused Russia of a serious provocation. Russia has said there is no evidence its drones were involved in the violation. Warsaw invoked NATO's Article 4 in response to the incident, formally starting consultations with allies on how to respond.
