Instead of spending Monday night in the Nigerian capital, Abuja, before flying back to Washington, Tillerson's spokesman said the secretary had changed his schedule so that he would spend only a few hours in Nigeria before leaving late in the evening to fly home. In April 2014, more than 200 girls were stolen from a school in Chibok, Borno State.
Tillerson was on Monday in Abuja, Nigeria on a visit.
Buhari's office said the president asked Tillerson for further support in terms of training and equipment, without elaborating.

Progress had been made with dealing with what has been cited as the reason for including Chad on the list - problems with its passports, which are not biometric.
The Secretary expressed concern about the recent attacks and abductions and agreed to expand counterterrorism cooperation to diminish the threats to USA and Nigerian interests.
