DUBAI: Bahrain’s Prince Khalifa bin Salman Al Khalifa, one of the world’s longest-serving prime ministers who led his island-nation’s government for decades and survived the 2011 Arab Spring protests that demanded his ouster over corruption allegations, died on Wednesday. He was 84.

Bahrain’s state-run news agency announced his death, saying he had been receiving treatment at the Mayo Clinic in the United States, without elaborating. The Mayo Clinic declined to comment.
