Tunisia has arrested 12 people, one of them a woman, who were trying to cross into Libya to join a "terrorist group", Reuters quoted the interior ministry as saying. After attacks on tourists by terrorist militants, Tunisia is especially concerned about those entering from Libya. Security forces arrested the 12 at a bus stop in the southern town of Ben Guerdane near the border with Libya, the ministry said in a statement late on Friday. "The suspects said that they had been planning to cross into Libyan territory with the help of a smuggler," it said.
