Tunis, Sep 17 : Tunisian Maritime Guard units foiled 1,976 illegal immigration attempts this year as of September 13, the National Guard spokesman Houcemeddine Jbabli said. "More than 21,500 illegal Tunisian and foreign immigrants, including 412 Tunisian minors, were arrested," Jbabli said in a statement on Friday, adding that 552 smugglers were arrested during the same period. "The scourge of illegal immigration is attracting more and more women, including pregnant women," he said.

Although Tunisian authorities have adopted rigorous measures to tackle the problem, the number of illegal immigrants who depart Tunisia for Italy has not decreased. /IANS
