Bujumbura - Burundi has been rocked since April 26 by protests over a bid for a third term by President Pierre Nkurunziza.
Since the start of the protests, more than 30 people have been killed and scores wounded in clashes between demonstrators and police and ruling party militia. More than 110 000 have fled to neighbouring countries.
The opposition says Nkurunziza's move is unconstitutional and goes against the peace deal that ended a civil war in 2006.
26 April, 2015: Police clash with protesters in several parts of the capital, a day after Nkurunziza is declared candidate for a third term in office by his ruling CNDD-FDD. Police use tear gas, water cannons and live ammunition to prevent thousands of youths from marching to the city centre.
Three demonstrators are shot dead in the clashes with police, while two further deaths are reported overnight in alleged attacks by ruling party militia.
27 April: Police arrest leading human rights activist Pierre-Claver Mbonimpa and hold him for 30 hours. Other rights leaders go into hiding.
5 May: The Constitutional Court clears Nkurunziza to run for a third term.
The judgement signed by six out of seven judges comes hours after the court's vice-president fled the country after refusing to sign the judgement, claiming judges had been subjected to death threats.
9 May: The government orders protesters to "immediately and unconditionally" end the protests and orders all barricades to be removed within 48 hours.
May 13: A top Burundian general, Godefroid Niyombare announces the overthrow of Nkurunziza, hours after the president left for neighbouring Tanzania for talks with regional leaders on ending the crisis. On 15 May, coup leaders announce that they are surrendering, before being arrested by loyalist forces. Niyombare avoids capture and goes on the run, according to the government.
Nkurunziza returns to the presidential palace in the capital.
18 May: Nkurunziza replaces the defence, foreign affairs and trade ministers.
20 May: Nkurunziza postpones parliamentary elections to 5 June, and says "peace and security reign over 99.9% of Burundian territory".
22 May: Attackers hurl grenades into a crowd in Bujumbura, killing three people, in the first such attacks to apparently deliberately target a civilian crowd.
23 May: The leader of a small Burundian opposition party - Zedi Feruzi - is shot dead with a bodyguard in Bujumbura's Ngagara district.
25 May: Demonstrators defy the police in the streets of Bujumbura and also in the provinces, where at least one protester is killed by the police.
