The United States delivered more than $25 million worth of military aid, including heavy artillery, to the Lebanese army on Sunday to help it fight jihadi groups that have repeatedly battled with security forces near the Syrian border.

The U.S. ambassador to Beirut, David Hale, said in a statement the weapons would be used to "defeat the terrorist and extremist threat from Syria."

"We are fighting the same enemy, so our support for you has been swift and continuous," Hale said at an event marking the delivery of the weapons in Beirut.
