Egyptian President Abdel-Fattah al-Sisi on Friday mourned the victims of the deadly attack on a bus heading to a Coptic monastery in Upper Egypt's province of Minya.

"I assert our determination to continue our efforts to combat dark terrorism and pursue the perpetrators," the Egyptian president wrote on his official Facebook page, wishing a speedy recovery for the injured.

The state media said at least seven Copts were killed and seven others wounded in an armed attack on a passenger bus heading to St. Samuel Monastery in the southern province of Minya.

No group has yet claimed responsibility for the attack.

Last year in the same place, at least 28 Copts were killed in a similar attack.

Sisi is currently in the Red Sea resort city of Sharm el-Sheikh to prepare for the opening ceremony of a three-day international youth forum scheduled to start on Nov. 3.
