African leaders in Pretoria for President Jacob Zuma's inauguration will hold informal talks on the security situation in Nigeria, South Africa's government said on Saturday.
Nigeria's President Goodluck Jonathan is among more than 20 heads of state gathered for the event.
Government spokesman Clayson Monyela said they would meet to discuss security in Nigeria, where the kidnapping of 276 schoolgirls has laid bare the government's inability to tackle an insurgency by the Islamist group Boko Haram.
The talks follow a spate of attacks in Nigeria, which is under growing international pressure to tackle the increasingly bloody uprising.
Jonathan was greeted with shouts of "bring back our girls" when he arrived at the Union Buildings, where Zuma was inaugurated.
