US vows 'consequences' for Russia over nukes

KYIV: An overnight drone strike near Odesa sparked a massive fire and explosion, Ukraine's military said on Monday, hours after the United States vowed to take decisive action and promised "catastrophic consequences" if Russia uses nuclear weapons in Ukraine.

The airstrike was the latest in a series of drone attacks on the key southern Ukrainian city in recent days. This one hit a military installation and detonated ammunition when it struck. Firefighters were struggling to contain the blaze, the Ukrainian military's southern command said.
