Nigerian government officials and the International Committee of the Red Cross have had talks with Boko Haram about swapping imprisoned members of the Islamist terrorist group for the more than 200 Chibok school girls kidnapped in April, a source involved in the negotiations told CNN. The officials met four times in mid-August with two senior members of Boko Haram in Nigeria's capital, Abuja. The swap would involve the release of 30 Boko Haram commanders in the custody of the Nigerian government, according to the source, who asked not to be named due to the sensitivity of the issue. Boko Haram submitted a list with the names of 30 members who were either convicted or awaiting trial on terror offenses.
