OUAGADOUGOU (Reuters) - Burkina Faso’s foreign minister said on Monday it had recalled its ambassador to Libya over a report that black African migrants were being auctioned as slaves there.

The decision by the West African nation followed the broadcast by CNN of footage of what it said was an auction of men offered to Libyan buyers as farmhands and sold for $400, a chilling echo of the trans-Saharan slave trade of centuries past.

Libya’s ambassador to Burkina Faso said his country was being unfairly blamed for a global problem that all nations affected must come together to solve.

Foreign Minister Alpha Barry announced the decision by President Roch Marc Kabore in a news conference.

“The president of Burkina Faso has decided to recall the ambassador to Tripoli, General Abraham Traore, for a consultation,” Barry said.

He had also “summoned the Libyan charge d’affairs in (Burkina Faso’s capital) Ouagadougou to express our indignation at these images that belong to other centuries, images of the slave trade”.

In a news conference on Wednesday, Libya’s ambassador to Burkina Faso, Abdul Rahman Khameda, appealed for help from both the European Union and African Union to help Libya reach a lasting resolution of the migrant crisis.

“Libya alone can not solve this problem,” he said. “We call on the international community to intensify efforts to help Libya cope with this danger (illicit migration), which is tearing at its social fabric.”

African and European leaders are due to meet next week in Ivory Coast’s main city, Abidjan, where migration and Europe’s efforts to tackle it by co-opting Libya will be high on the agenda.

“Adopting an effective solution will prevent certain parties from exploiting such unfortunate events to tarnish Libya’s name,” Khameda said.

An agreement between Europe and Africa to stem the flow of migrants coming through Libya to Europe had failed to tackle the severe abuses they face, the U.N. High Commissioner for Human Rights Zeid Ra’ad al-Hussein wrote in an article published in September.
