KHARTOUM (AFP) -- Sudanese security forces shot dead two protesters in a crackdown on rallies against last year’s military coup and the arrest of scores of pro-democracy activists, medics said. Regular mass protests have rocked the troubled northeast African nation since an October 25 military takeover led by army chief Abdel Fattah al-Burhan, and the deaths on Monday take the number killed in the unrest to at least 81. Thousands rallied in the capital Khartoum and its twin city of Omdurman, while protests also took place in the eastern city of Port Sudan and in the western Darfur region, according to witnesses.
