UAE leader Sheikh Khalifa bin Zayed Al Nahyan dies aged 73

The United Arab Emirates' long-ailing ruler and President, Sheikh Khalifa bin Zayed Al Nahyan, has died at the age of 73. 

Sheikh Khalifa oversaw much of the country's blistering economic growth and his name was immortalised on the world's tallest building,

However, after suffering a stroke and undergoing emergency surgery in 2014,

a decade after becoming President, he ceased having any involvement in the day-to-day affairs of ruling the country.

The last several years of his life saw his half-brother,

Abu Dhabi Crown Prince Mohammed bin Zayed, rise to become the de-facto ruler and decision-maker of major foreign policy decisions,

such as joining a Saudi-led war in Yemen and spearheading an embargo on neighbouring Qatar.
