He told of how Sgt Omar Khalifa Al Ketbi had died responding to a fire in Al Aweer district, in a message posted on social media on Saturday. "Our firefighters sacrifice their lives to save others and to protect our nation," Sheikh Hamdan wrote on Twitter, accompanied by a black and white image of the officer. "Dubai will remember Sergeant Omar Khalifa Al Ketbi, who passed away while on duty responding to a fire in Al Aweer." Crews from Al Mizhar, Rashidiya and Nad Al Shiba fire stations were called to a fire at Al Kabayel Discount Centre at 12.32pm on Friday, Dubai Media Office said in a statement issued later on Saturday evening.
