BRUSSELS (AP) — As war rages on in Ukraine, President Joe Biden will huddle with key allies in Brussels and Warsaw this week to talk through plans for imposing punishing new sanctions on Russia and dealing with an extraordinary humanitarian crisis, while developing a consensus on how they would respond if Russia were to launch a cyber, chemical or even nuclear attack.

Biden arrived in Brussels on Wednesday for a four-day trip that will test his ability to navigate Europe’s worst crisis since World War II ended in 1945. There are fears that Russia could use chemical or nuclear weapons as its invasion becomes bogged down in the face of logistical problems and fierce Ukrainian resistance.
