Washington - The United States hit back Wednesday at allegations by the Nigerian ambassador of failing to help fight Boko Haram militants, saying there had been "a great deal" of US aid to his country. In the past six months since the Islamic militants snatched some 200 schoolgirls in northern Nigeria, Washington has shared intelligence with the Nigerian army, begun training a new battalion and held high-level talks on the threat of Boko Haram, a US official said. In a speech made public Tuesday, ambassador Adebowale Adefuye appeared to have taken US officials by surprise when he launched into a tirade against the US administration. Nigerian leaders were "not satisfied with the scope, nature and content of the United States' support for us in our struggle against terrorists," he said. He accused Washington of not providing the "lethal" weapons needed to deliver "a killer punch" to the militants. Also Read: Success of 2015 elections to de...
