We’re
looking into reports an oil refinery is on fire in Ryazan, a city around 110
miles (180km) south-east of Russia’s capital Moscow. It’s the same plant that
was struck by Ukraine last weekend forcing it to suspend operations. The
governor of Ryazan region has reported drones being shot down overnight, saying
debris from one caused a fire to break out at a business.

Images
showing a blaze at a petrochemical facility in Venezuela on Wednesday are being shared online which we are
verifying. According to Reuters, an explosion was heard before the fire. It’s
being reported that no-one was injured and it is not
clear yet what caused the incident.

And
we’ve been investigating why the AI chatbot Grok has been telling users of the
social media platform X that US President Donald Trump did not say “quiet
piggy” to a reporter. Grok has been falsely saying Trump said “quiet, Peggy” –
but there are reasons why that’s not true.

We’ll
have more from the BBC’s team of fact-checkers, verification specialists and
data journalists throughout the day.
