An outspoken critic of Tunisia’s Islamist government was shot dead outside his home Wednesday, underscoring a deepening political rift between newly empowered Islamists and their secular opposition in states across North Africa since the Arab Spring.

Chokri Belaid, an opposition leader with the leftist Popular Front coalition, was assassinated in Tunis a day after he received the latest in a string of death threats and called for a national conference on political violence.

Critics of Islamists or Islam get killed, exiled, imprisoned, silenced. Sometimes I feel that soon or later the world will turn into a ‘land of Islam.’
