A group of more than 300 doctors from around the world are calling on U.K. Home Secretary Priti Patel to block the extradition of Julian Assange to the United States. In a letter to Patel, the group known as Doctors for Assange says the WikiLeaks founder suffered a mini stroke last October and that his overall health is continuing to deteriorate in prison. The doctors write, “The extradition of a person with such compromised health, moreover, is medically and ethically unacceptable.” Patel is expected to rule on Assange’s extradition by Friday.
