Vladimir Putin has issued a warning against the UK and US lifting their restrictions on Ukraine using long-range missiles against targets inside Russia. Britain and France have already sent Storm Shadow missiles to Ukraine, but with the caveat that Kyiv can only fire them at targets inside its own borders.

From the tone of President Putin’s latest remarks, it’s clear he considers that the targeting of internationally recognised Russian territory with Western missile systems would take the conflict to a new level. What he didn’t make clear is how Moscow would respond.

Also in the programme, authorities in Nigeria Borno State say up to two million people affected by floods after the collapse of a dam earlier this week during heavy rainfall; and it's time for the tongue in cheek Ig Nobel awards - amusing studies with serious implications.
