Security forces arrested a Salafist tied to the September 2012 attack on the US Embassy, and also arrested a terrorist linked to the assassination of secular leader Chokri Belaid. Several Tunisian politicians and journalists said they have recently received assassination threats. A report estimated that there are 50 active and sleeper terrorist cells in the country, with 600 to 700 members. The report also said that of roughly 600 Tunisian foreign fighters with al Qaeda in the Islamic Maghreb, about 200 are in Algeria, Mali, and Libya; 300 are fighting in Syria, Iraq, Yemen, and Egypt; and 100 others are in Pakistan and Afghanistan. The report alleged that AQIM’s Tunisian foreign fighters were waiting for a signal from al Qaeda to return home to fight.
