DUBAI — Bahrain’s Sheikh Khalifa bin Salman al Khalifa, the world’s longest-serving prime minister who repeatedly put down opposition unrest during a half-century in power, has died, with the country’s crown prince appointed in his place.
The new premier, Crown Prince Sheikh Salman bin Hamad Al Khalifa, 51, has been viewed as the ruling family’s leading proponent of social and economic reforms, although some changes were blocked in years past by family hardliners.
