Us agrees train nigerian troops anti terror war

I think there may be a slight mistake in your question. The correct phrase is likely "US agrees to train Nigerian troops in anti-terrorism war".

To clarify, the United States has indeed agreed to provide training and assistance to the Nigerian military in their fight against Boko Haram, a terrorist group that has been responsible for numerous attacks and kidnappings in Nigeria and the surrounding region.

In 2015, the US government announced that it would provide $5 million in military assistance to Nigeria to help the country combat Boko Haram. This assistance included training and equipment for the Nigerian military, as well as support for regional counter-terrorism efforts.

Since then, the US has continued to provide training and assistance to the Nigerian military, with a focus on improving their capabilities in areas such as intelligence gathering, logistics, and tactical operations. The goal of this assistance is to help the Nigerian military more effectively counter Boko Haram and other terrorist groups, and to protect civilians from their attacks.

It's worth noting that the US has also provided humanitarian assistance to Nigeria and other countries affected by Boko Haram's activities, including support for refugees and internally displaced persons.
