Vladimir Putin is set to begin sending supplies to Iran in a bid to bolster the Islamic Republic's war effort against the US and Israel.

Security officials told the Financial Times that Russia would only be able to supply a handful of different types of drones, including the Geran-2 and the so-called "kamikaze" Shahed-136 models.
When probed about the potential supply of aircraft, Kremlin spokesman Dimitry Peskov refused to confirm or deny the reports.
He said: "There are a lot of fakes going around right now.

Mr Zelensky said: "I have reports from our intelligence services showing that Russia is doing this and saying: 'I will not pass on intelligence to Iran if America stops passing intelligence to Ukraine'.
"Isn't that blackmail? Absolutely."
