Thousands of Sudanese protested outside the presidential palace in Khartoum on Thursday, calling for the appointment of senior judicial officials and justice for demonstrators killed since December.
It was the first major protest since the signature last month of a power-sharing deal between the military and civilian groups for a three-year transition leading to elections, following the overthrow of former president Omar al-Bashir in April.
Police had blocked protesters in central Khartoum about 200 meters from the palace, but they surged past a barbed wire barrier to the palace gates. Police later fired tear gas to disperse them, Reuters witnesses said.
