Istanbul’s Hagia Sophia holds first Muslim prayers in 86 years

President Erdogan of Turkey has joined huge crowds in Istanbul, for the first Friday prayers at Hagia Sophia since the 1,500-year-old former church was turned back into a mosque. The Pope has expressed his sadness at the move – while church bells rang out in neighbouring Greece, which called it an “open provocation to the civilised world”.
