Bahrain vowed on Tuesday to crack down harder on anti-government protests as a leading opposition figure said the government had put a stop to talks on addressing the political grievances that fuelled last year’s pro-democracy uprising. Bahraini media have reported a new security plan to “restore order” and, in recent days, authorities have detained a leading protester and warned a cleric to stop alleged incitement to violence. Bahraini government spokesman Shaikh Abdulaziz bin Mubarak Al Khalifa said: “Because of the escalation in violence, we are looking into the perpetrators and people who use print, broadcast and social media to encourage illegal protest and violence around the country.”
