Saudi king's son Mohammed bin Salman is new crown prince

Saudi Arabia has typically been ruled by kings in their 70s or 80s.
Prince Mohammed bin Salman's rapid ascent is seen by the younger generation as a sign that things are changing.
Before his latest promotion, he was responsible for leading Saudi Arabia's war in Yemen, overseeing the kingdom's energy policy and economic reform.
He must have already ruffled a lot of feathers in a royal family that was used to being presided over by a succession of elderly men, the BBC's Middle East editor Jeremy Bowen reports.
