A Tunisian gendarme stands guard outside a house where two suspected jihadists were killed during a security operation on May 11, 2016 in the town of Mnihla, in Ariana province just outside Tunis. Sixteen others, some of them armed, were arrested during the operation, the interior ministry said in a statement. Since its 2011 revolution, Tunisia has faced a growing jihadist threat, with the Islamic State group last year claiming a string of deadly attacks on holidaymakers and security forces that killed dozens. / AFP / FETHI BELAID (Photo credit should read FETHI BELAID/AFP/Getty Images)
