African countries could set up a special fund to combat Islamist militant groups, the continent leaders proposed on African Union Peace and Security summit in Nairobi.
Kenya's President Uhuru Kenyatta said African countries should stand together against the threat of Boko Haram and Al-Shabaab.
Al-Shabaab militants killed 67 people in a raid on a shopping mall in Kenya last September.
"No single state can tackle this threat alone," Mr Kenyatta said. "It is particularly worrying in Africa today that terrorist organizations have grown both in terms of number and capability."

The idea of a common African fund to combat terrorism was mooted by Mr Kenyatta and would be discussed at the next African Union summit.
