Nigeria: two weeks of spiralling protests
For two weeks Nigeria has been rocked by protests that erupted against police violence and evolved into broader anti-government demonstrations led by the country's youth, triggering a deadly crackdown.
Here is a recap:
Video goes viral
On October 3, a video spreads on social media showing what looks like an officer from the federal Special Anti-Robbery Squad (SARS) attacking a young man in the southern town of Ughelli, in Delta state.
The video goes viral and leads thousands of people to go online and share their own stories of police abuse.
In a matter of days, the hashtag #EndSARS tops the global trends on Twitter, supported by world famous Afrobeat pop stars like Davido and Wizkid.
Protests
On October 8, security forces crack down on protests that break out across the country. In Ughelli one protester and one police officer are killed in the clashes.
The next day, hundreds of people take to the streets in several major cities to protest against police violence.
One person is killed by security forces on October 10 in Ogbomoso, in the southwestern Oyo state.
Squad dissolved
On October 11, demonstrations grow and several protests are organised by the Nigerian diaspora, notably in London.
President Muhammadu Buhari, bowing to pressure, announces that SARS will be dissolved.
The government says a new SWAT unit will replace SARS, with promises that it will be "ethical", and police abuses will be investigated and prosecuted.
Growing unrest
The announcements do not appease protesters and the next day thousands of people take to the streets in several cities.
Demonstrators have made five demands that include structural police reforms and better pay for officers.
Many demonstrators are also calling for more sweeping change in Nigeria, which has the largest number of people living in extreme poverty in the world and massive youth unemployment.
In Surulere, in Lagos state, one protester and one police officer are killed in clashes, according to the Lagos state government.
Road blocks, army warning
On October 13, thousands of people demonstrate in a string of cities, bringing traffic to a standstill in economic hub Lagos.
Two days later the military issues a warning to "troublemakers" and says it "remains highly committed to defend the country and her democracy at all cost".
Protests continue, with flag-waving crowds heading towards the national assembly in the capital Abuja and people gathering to block traffic on key roads in Lagos.
The sprawling megacity of 20 million is paralysed on October 19 when protesters block the airport and most major roads, causing huge traffic jams. Schools are shut.
'Thugs'
Protesters around the country have repeatedly complained that "thugs" believed to have been paid by local officials have violently broken up rallies.
In Benin City in southern Edo state, police say two of their facilities were attacked on October 19 by "persons posing as #EndSARS protestors".
Twelve suspects are arrested after the incident and the local governor imposes a 24-hour curfew.
Lagos curfew, deaths
On October 20, protests turn violent in cities including Lagos and Abuja.
A round-the-clock curfew is imposed in Lagos and anti-riot police units are deployed nationwide.
That evening more than 1,000 people defy the curfew and gather at Lekki tollgate in Lagos, the epicentre of the demonstrations.
Several protesters are killed by security forces, according to Amnesty International.
On October 21 the Lagos governor initially says 25 people were wounded but that there were no fatalities. He later says the authorities are investigating the death of one person who suffered "blunt trauma" to the head.
International condemnation
As unrest spreads in Lagos, a major TV station, TVC, linked to one of the ruling party's top politicians is among buildings set ablaze.
International condemnation of the killing rolls in, with the UN Secretary General Antonio Guterres calling for an end to "brutality" by police in Nigeria, and pointing to "multiple deaths".
The European Union's foreign policy chief Josep Borrell says: "It is crucial that those responsible of abuses be brought to justice."
In South Africa hundreds of people take to the streets to voice outrage at the shooting.
In the evening, Amnesty International says the Nigerian army and police killed at least 12 peaceful protesters at two locations in Lagos.
