[Updated at 3:12 p.m. ET] Tunisia's prime minister Hamadi Jebali resigned Tuesday, Tunisia state TV said, marking the latest development in a nation wracked by political unrest.

He submitted his resignation after the failure of his initiative to form a technocratic government, state TV reported. Jebali told CNN last week he'd step down if the effort was not approved.

It's possible that his ruling Muslim Brotherhood-linked Ennahda party will reappoint him to form another government or choose another politician to do the task.
