DUBAI: Sheikh Khalid bin Sultan Al-Qasimi, the son of the ruler of Sharjah, died in London on Monday, UAE state news agency WAM reported.
Sharjah Media Office confirmed in a tweet that Al-Qasimi, who was 39, had died, without giving any further details.
He served on a number of governing bodies including the Sharjah Urban Planning Council, which he chaired and he led work on the Sharjah Architecture Triennial exhibition.
Three days of mourning have been announced in the emirate, which will start when the sheikh’s body arrives in Sharjah.
The funeral date will be announced later.
Sheikh Khalid was the co-owner of a London-based fashion label Qasimi. The company on Tuesday posted a tribute to its founder and creative director on Instagram.
"Khalid was praised for his tenacious yet sensitive exploration of social-political issues, particularly those pertaining to the Middle East and its sometimes strained relationship with the West, a subject very close to his heart and his upbringing," the statement said.
"His goal was to create a world full of beautifully crafted products infused with cultural, social and political undertones to inform and inspire.
"The design world has lost a great philosopher and artist, and we ask that the privacy of the family, team and brand are respected at this difficult time."
