LONDON, Dec 21 (Reuters) - Countries across Europe considered new curbs on movement on Tuesday as U.S. President Joe Biden called on military medics to support hospitals and fight the Omicron variant that has swept the world days before the second Christmas of the pandemic.
Omicron infections are multiplying across Europe, the United States and Asia, including in Japan, where a single cluster cases at a military base has grown to at least 180.
