Russia's central bank sharply raised its key rate Monday in a desperate attempt to shore up the plummeting ruble and prevent the run of banks amid crippling Western sanctions over the Russian war in Ukraine.

The bank hiked the benchmark rate to 20% from 8.5%. That followed a Western decision Sunday to freeze Russia's hard currency reserves, an unprecedented move that could have devastating consequences for the country's financial stability.

In a dramatic escalation of East-West tensions over Russia's invasion of Ukraine, President Vladimir Putin ordered Russian nuclear deterrent forces put on high alert Sunday in response to what he called "aggressive statements" by leading NATO powers.

The order means Putin has ordered Russia's nuclear weapons prepared for increased readiness to launch, raising the threat that the tensions could boil over into a nuclear war. In giving it, the Russian leader also cited hard-hitting financial sanctions imposed by the West against Russia, including Putin himself.

Lebanon has wheat reserves sufficient for one month at the most, with Ukraine accounting for up to 60 percent of the crisis-hit country's wheat market, the economy minister said on Friday.

Concerns about wheat reflect the rippling effect of Russia's invasion of Ukraine. The Lebanese government is in talks with other countries like the United States, India and Canada to provide wheat amid concerns of global disruption to wheat supply during the crisis, the Minister, Amin Salam, said.

The Kremlin says prospects for possible peace talks between Russia and Ukraine look uncertain due to apparent differences over a venue.

Kremlin spokesman Dmitry Peskov said Friday that Russian President Vladimir Putin has agreed to send a delegation for talks with Ukrainian officials in Minsk, Belarus, where President Alexander Lukashenko runs a pro-Russian government.

U.S. and European officials are holding one key financial sanction against Russia in reserve, choosing not to boot Russia off SWIFT, the dominant system for global financial transactions.

The Russian invasion of Ukraine caused a barrage of new financial sanctions Thursday. The sanctions are meant to isolate, punish and impoverish Russia in the long term. President Joe Biden announced restrictions on exports to Russia and sanctions against Russian banks and state-controlled companies.

It has been a long time since the threat of using nuclear weapons has been brandished so openly by a world leader, but Vladimir Putin has just done it, warning in a speech that he has the weapons available if anyone dares to use military means to try to stop Russia's takeover of Ukraine.

The threat may have been empty, a mere baring of fangs by the Russian president, but it was noticed. It kindled visions of a nightmarish outcome in which Putin's ambitions in Ukraine could lead to a nuclear war through accident or miscalculation.

Dubai will open the doors Friday to an architecturally stunning building housing the new Museum of the Future, a seven-story structure that envisions a dreamlike world powered by solar energy and the Gulf Arab state's frenetic quest to develop.

The torus-shaped museum is a design marvel that forgoes support columns, relying instead on a network of diagonal beams. It is enveloped in windows carved by Arabic calligraphy, adding another eye-popping design element to Dubai's piercingly modern skyline that shimmers with the world's tallest tower, the Burj Khalifa.

The husband of a cinematographer shot and killed on the set of the film "Rust" says it's "absurd" that Alec Baldwin believes he's not to blame for the shooting and he was "so angry" when Baldwin didn't accept responsibility.

The remarks made in excerpts from an interview with the "Today" show are the first public words from Matt Hutchins on the Oct. 21 death of his wife Halyna Hutchins.

To say Naomi Watts is the only star in "The Desperate Hour" is a little misleading. She's pretty much the only person in the film, that's true. But you could make the case that she has a co-star in her iPhone.

Watts spends most of "The Desperate Hour" furiously typing, listening, consulting, pleading or otherwise glued to her smartphone as it takes on an outsized importance. Alone and lost in the woods, it's her only lifeline to the world.

The logo of Russian state-owned energy giant Gazprom is being removed from the jerseys of German soccer team Schalke following Russia's wide-ranging attack on Ukraine on Thursday.

Schalke said the logo will be replaced by lettering reading "Schalke 04" instead following what it called "recent developments."
