TUNIS — The Tunisian government will shutter unsanctioned mosques and organizations that could have ties to Islamic extremism, step up security at tourist spots and deploy troops elsewhere in the wake of the country's worst terror attack ever."The fight against terrorism is a national responsibility," Prime Minister Habib Essid said Saturday as his government announced a raft of new measures. "We are at war against terrorism which represents a serious danger to national unity during this delicate period that the nation is going through."
