Thousands of people have protested in Sudan to demand justice for pro-democracy demonstrators who were killed earlier this year.
The crowd gathered outside the presidential palace in the capital, Khartoum, on Thursday.
They chanted slogans, waved flags, and also called for the appointment of new senior judiciary officials.
Sudan has been in turmoil since long-time ruler Omar al-Bashir was ousted by the military in April.
More than 100 demonstrators were killed in June, doctors say, when the security forces dispersed a sit-in outside the defence ministry.
The unrest on Thursday was the first major protest since civilians and the military signed a power-sharing deal last month.
The landmark agreement ushered in a new governing council, which includes both civilians and generals, and will pave the way towards eventual elections and civilian rule.
On Thursday, police blocked protesters near the palace but the crowd broke through a barbed wire barrier.
Police later fired tear gas in an attempt to disperse them, witnesses told Reuters news agency.
