An American citizen has died in an Egyptian prison after a series of lengthy hunger strikes protesting his imprisonment. Moustafa Kassem was arrested in 2013 amid a massive crackdown following Abdel Fattah el-Sisi’s military takeover of Egypt. Kassem said he had no links to politics or opposition groups, but he was sentenced to 15 years in prison on political charges he said were false. He died on Monday. Egypt is the second-largest recipient of U.S. military aid, after Israel. President Trump has frequently praised Egyptian leader el-Sisi, even as he has imprisoned tens of thousands of people on political charges since 2013.
