The United States plans to give Tunisia $60 million in military aid to help the country meet a threat by Islamic militants.
U.S. Africa Command head General David Rodriguez said Tuesday the assistance includes mine-detecting equipment, boats, and joint U.S.-Tunisian military training.
The State Department has already approved the sale of 12 Black Hawk attack helicopters to Tunisia.
Tunisia was the first North African country to topple its government in a popular uprising in 2010 and has been relatively peaceful since.
But it faces a terror threat by al-Qaeda-linked militants and fears the instability in neighboring Libya could spill across the border.
Rebels from Mali have also taken refuge the mountains in Algeria, along Tunisia's western border.
