The United States condemns the April 20 attack on a clearly-marked UN vehicle in Rakhine State, which resulted in the death of one World Health Organization (WHO) employee and the wounding of a health worker. We understand these Burmese nationals were working to fight the COVID-19 pandemic when they came under attack. This egregious act undermines efforts to protect vulnerable populations in Burma and again highlights the urgent need for a cessation of fighting in Rakhine State. It also hinders global efforts to stop the spread of the virus. We urge Burmese authorities to investigate the incident and bring the perpetrators to justice. Health and humanitarian workers across the globe must be able to work without threat of violence – now more than ever.
