The death toll from a stampede by a mob in Nigeria's southeastern town of Okiya has risen to 22, police said.
This is the third case this week of people being crushed to death at free food events.
The deaths in Okija happened at a charity event on Saturday as residents rushed to collect Christmas donations, including rice and vegetable oil.
On the same day, a similar tragedy at a Catholic church in the capital, Abuja, killed 10 people while 35 children died during a carnival event on Wednesday in the city of Ibadan.
Police have already warned organizers to notify the authorities before organizing charity events to prevent such loss of life.
Toyin Abdul Kadri, who witnessed the disaster at the Holy Trinity Catholic Church in Abuja, told AFP that those present “forced open the gates and got inside”.
The event involved “vulnerable and elderly people” and four children were killed, police said.
In a social media post about the devastation, Amnesty International Nigeria wrote: “The government of President Bola Tinubu must urgently prioritize addressing widespread hunger, higher unemployment and rapidly falling living standards.”
Food and transport costs have more than tripled in Nigeria in the past 18 months.
The global bout of inflation has been exacerbated by some of the government's policies – designed to strengthen the economy in the long term – such as ending the fuel subsidy.
In a statement on the deadly clashes, President Bola Tinubu said: “In a season of joy and celebration, we mourn with fellow citizens who mourn the painful loss of their loved ones. Our prayers for divine comfort and healing are with them.”
He called on state governments and the police to impose strict crowd control measures and canceled all official engagements in honor of the victims.
He also noted the similarities between the incidents, including one earlier this week in the southwestern city of Ibadan.
A falling in love at a school fair there he killed 35 children and seriously wounded six others.
Thousands of people had turned up with the promise of free food.
Residents of Bashorun, a suburb of Ibadan, told the BBC that the crowd soon exceeded 5,000, with many trying to force their way through the school gate. The parents are said to have tried to jump over the fence around the compound to gain access.
Police spokesman Olumuyiwa Adejobi said the three “tragic” incidents highlighted “the urgent need for a more structured and effective approach to providing assistance to vulnerable communities and members of society at large”.
