The United Kingdom is paying tribute to the first doctors on the front lines of the coronavirus pandemic who have died after contracting COVID-19.
All four men - Alfa Sa'adu; Amged el-Hawrani; Adil El Tayar and Habib Zaidi - were Muslim and had ancestry in regions including Africa, Asia and the Middle East.
Dr Salman Waqar, the general secretary of the British Islamic Medical Association, said the contribution of these doctors was "immeasurable".
"They were devoted family men, committed senior doctors, and dedicated decades of service to their communities and patients," he said.
"They gave the ultimate sacrifice while fighting this disease. We urge everyone to do their part and stop further deaths from happening - stay at home, protect the NHS, save lives."
As the country fears a shortage of medical staff amid the pandemic, which has so far killed 2,352 people and infected 29,474 according to government figures, the loss of the doctors has highlighted the vital contribution of medics from minority backgrounds to the UK's National Health Service (NHS).
The NHS is the largest employer of Black and Minority Ethnic (BME) staff in the UK with 40.1 percent of medical workers from BME backgrounds.
Priti Patel, the home secretary, announced on Tuesday that about 2,800 medical staff whose visas expire before October 1, will have their visas extended for a year "free of charge".
