"The army has launched an assault on the palace in Carthage where elements of the presidential guard have taken refuge," the senior source said on condition of anonymity.
A witness in the area said by phone he had heard "an exchange of fire" nearby. He said the army had set up a large security cordon outside the palace.
Another witness said she had seen "at least two helicopters flying over the presidential grounds."
State television reported that police officers sheltering inside a business school near the palace had asked the army to intervene. (*)
