Weather will vary widely across the U.S. as we head into the holiday week.

Russian forces are preparing to capture the capital of Zaporizhzhya, a southern Ukrainian region illegally annexed by Moscow and largely under Russian control, President Vladimir Putin said on Monday. Russian troops are already 15 kilometres south of the border of the regional capital, which is also called Zaporizhzhya, military officials reported at a meeting with Putin.

Ukraine's soldiers are trained by Western allies, but they have also ended up teaching those allies how to fight a modern war.
