Russia warns Western forces deployed to Ukraine under postwar security deal would be "legitimate combat targets" as diplomatic tensions escalate.

In U.S. dollar terms, that “cost” is a staggering $11.9 billion hit to the Russian economy. To put that into perspective, Venezuela is second-placed, taking a much more modest $1.91 billion hit to its already ravaged economy.

The U.S. striking Venezuela and capturing its leader has practical implications for China, Russia, Iran and Cuba, and it also sends messages to each nation.

The lightning U.S. operation to capture Venezuelan leader Nicolas Maduro can be seen as both a benefit and a burden for Russian President Vladimir Putin, whose forces botched an attempt to capture Ukraine’s capital and topple its leader at the start of Moscow's invasion nearly four years ago.

NATO allies in the Coalition of the Willing are planning security guarantees for Ukraine once Russia's war is over.

First Minister John Swinney has backed action to enforce sanctions against Russia following the US seizure of a Russian-flagged tanker in the North Atlantic. The Marinera, a ship accused of being part of Vladimir Putin's "shadow fleet", was intercepted by the US Coast Guard a few hundred miles off the Scottish coast.

More Russian attacks struck Ukraine Tuesday night. The attacks came a day after the Coalition of the Willing meeting in Paris. The Coalition is a group of Ukraine's allies aiming to help defend the country against Russian aggression.
