Boko Haram member says girls will not be released until prisoners are freed. 

When pressed on whether abducting the girls and forcing them to convert to Islam is the same as forcing them, he said, "As I tell you, we are not forcing anyone to accept Islam. We are just preaching to them."

He said the girls would be held captive until the Nigerian government released Boko Haram fighters from prison. "If Allah wish, nothing will happen to them," he said. "But we ask the government if they don't release our brothers, we are not going to release them."

Asked whether the girls will be killed if the government does not release the prisoners, he replied, "I will not tell you what we are going to do."
