President Muhammadu Buhari on Monday received US secretary of state, Rex Tillerson, at the presidential villa in Abuja.
The meeting started after Buhari returned from a visit to Benue state.
The president had gone to condole with the state after suspected herdsmen killed over 70 people in the state in January.
According to a statement by his Special Adviser on Media and Publicity, Mr. Femi Adesina, the President said that Nigeria was working in concert with international organisations and negotiators to ensure that the girls were released unharmed by their captors.
“We are trying to be careful. It is better to get our daughters back alive,” the President said.
Buhari thanked the US for assistance rendered in the fight against insurgency, noting that Nigerian forces are good, “but need assistance in the areas of training and equipment.”
The President promised that his administration would continue to do its best to secure the country, adding that he would be in Yobe State, from where Dapchi schoolgirls were abducted, later this week “as part of my condolence and sympathy visits to areas where we have had unfortunate events.”
