The head of the World Health Organisation has told the BBC that it was public knowledge he was in Yemen on Thursday when Israel launched airstrikes on Houthi targets. Dr Tedros Adhanom Ghebreyesus said the main target, the International Airport in Sanaa was a civilian facility and should not have been hit.

Also in the programme: Taliban forces from Afghanistan are reported to have clashed with Pakistan's army on their border as tensions between the two countries grow; the phenomenon of mass violent attacks in China; and a new BBC documentary about Maria Callas, one of the greatest opera singers of the 20th century and why her amazing talent didn't last longer.
