MONTREAL - Two Montreal teens facing terrorism-related charges will remain behind bars pending their next court appearance in September.

Eighteen-year-old El Mahdi Jamali and nineteen-year-old Sabrine Djermane were not in court today when a date was set for a meeting where both sides will specify how many witnesses they expect to call.

They have been detained since their arrests in mid-April and were denied bail last month.

Jamali and Djermane each face four charges: attempting to leave Canada to commit a terror act abroad; possession of an explosive substance; facilitating a terrorist act; and committing an act under the direction or for the profit of a terrorist organization.

The two students at College de Maisonneuve, a Montreal junior college, were arrested as what the Crown called a "preventive measure."

Prosecutors wanted them to sign peace bonds that would set out conditions and restrictions on their day-to-day lives. Several days after their arrest, they reappeared before a judge to face the criminal charges.
