In a letter tweeted by the museum this week, Piotr Cywiński asked Nigerian President Muhammadu Buhari to pardon the boy, who was accused of blasphemy during a dispute with a friend and sentenced last month by an Islamic court in Nigeria’s northern Kano region, Polish Radio’s IAR news agency reported.
Cywiński said that if a pardon was not possible, he and 119 other volunteers would share the boy’s punishment and each spend a month in a Nigerian jail.
As the head of a memorial to Auschwitz, a place “where children were imprisoned and murdered, I cannot remain indifferent to this disgraceful sentence for humanity,” Cywiński added.
Reuters news agency reported that Buhari has not yet commented on the sentence that was condemned by rights groups.
UNICEF last month said the sentence was “wrong” and went against international accords that Nigeria had signed, according to Reuters.
In Nigeria, Muslims form the majority in the north, while the country’s southern parts are predominantly Christian.
