After spending the entire night being interrogated by counter-terrorism police, the leader of the largest party in the now-disbanded Tunisian parliament has been freed by the authorities.
Rached Ghannouchi has been accused of complicity in smuggling jihadists to Syria and Iraq, charges he has denied.
According to his lawyer, he will again be questioned later on Wednesday.
His Ennadha party has denounced his interrogation and that of the former prime minister, Ali Laarayedh, as a flagrant violation of human rights.
The Tunisian president, Kais Saied, has brooked no opposition to his rule since dissolving parliament last year.
