[Al Jazeera] Authorities in Nigeria have deployed special police forces to northern Kaduna and declared a 24-hour curfew in the state's capital following communal violence that killed dozens of people. President Muhammadu Buhari ordered the deployment on Sunday, as the regional government imposed the measure in Kaduna city after violence broke out on its streets.
The festivities followed violence that broke out on Thursday between Moslem and Christian communities in the Kasuwan Magani area of southern Kaduna which left at least 55 people dead.
"The violence in Kaduna ... is condemnable. The police have been authorised to do everything possible to restore calm. A Special Intervention Force has been deployed to the flashpoints," Buhari said on Twitter.
"The federal government and its law enforcement agencies will work with the state government and community leaders to ensure the full restoration of peace and security," Buhari said in another message.
