Washington: The United States will conduct surveillance and intelligence operations against Boko Haram inside Nigeria, sources familiar with the plan said on Friday, a significant escalation of Washington's role in combatting the Islamist group.
The operations will be carried out as part of the recently announced deployment of up to 300 US military personnel to neighboring Cameroon, officials said.
"This is going to be part of our Boko Haram efforts that will be operating throughout the region," one of the sources said on condition of anonymity.
It will not include boots on the ground or offensive combat, but will see US military operations against Boko Haram in Nigeria for the first time.
"It's surveillance and intelligence gathering, not anything offensive," said the same source.
US President Barack Obama on Wednesday announced 90 US personnel had already been sent to Cameroon and may eventually number up to 300.
The White House has been at pains to stress that personnel would not take part in combat operations and would be armed only for self-defense.
Nigeria greeted that announcement as a "welcome development."
President Muhammadu Buhari took office in May vowing to end the violence that has killed scores and spooked much-needed international investors.
