An event to remember 21 protesting coal miners killed 70 years ago by colonial troops has been held in Nigeria.
Workers at the Iva Valley Coalmine in Ogbete, a suburb of the south-eastern city of Enugu, had been demanding a salary increase at the time.
But the authorities accused them of organising a rebellion against British colonial rule.
"I was on duty when I saw the colonial military as they approached the mining site - and I sensed trouble," survivor Ogbonnaya Eze, who is now 110, told the BBC.
"I alerted the other miners around me to escape from another direction. We fled to a nearby bush and hid ourselves and from our hiding place, we heard the cackling of gunshots."
Godwin Aniagbo, an 85-year-old retired miner who was at secondary school in Ogbete on that day in November 1949, told the BBC he remembered hearing the sound of gunfire.
Some people say the victims' families were never compensated, but Mr Aniagbo says the colonial government gave them £400 each and says some of their children were offered scholarships.
Apart from a monument to the miners in Enugu, very little is left to remember them.
It is believed they were the forerunners of the labour union movement in Nigeria, which gained independence from the UK in 1960.
A seminar to educate secondary schoolchildren and others about the incident was held in Enugu on Monday - the date of the 70th anniversary.
And a local non-government organisation, the Centre for Memories, published the names of the 21 coal miners who had died - along with the jobs they had been assigned at the mine.
