Police and soldiers have deployed in large numbers in the Tunisian capital after deadly clashes with radical Islamists during the night, according to the interior ministry. The deployment came a day after Tunisia's state news agency said one protester was killed and three security officers injured in clashes near Tunis. Wielding sharp tools and swords, the protesters went on the attack in the Tunis suburb of Manouba after police arrested a Salafist suspected of assaulting the head of the suburb's public-security brigade, Khaled Tarrouche, interior ministry spokesman, said.
