It's a crackdown on despots and dictators.

The United Kingdom's government has announced its first sanctions since leaving the European Union.

They punish the perpetrators of what it calls "the gravest human rights offenders".

The targets include suspects linked to the killing of Saudi journalist Jamal Khashoggi, and Russians connected to the killing of tax fraud whistle-blower lawyer Sergei Magnitsky.

The Kremlin is promising retaliation.

But will sanctions change anything?
