Egypt's President Abdel-Fattah El-Sisi issued a statement on his official Facebook page on Friday mourning the victims of the terror attack on a bus carrying Copts on Friday.

"I mourn with deep sorrow the martyrs who were killed today by treacherous hands which aim to undermine the solid fabric of the nation, and I wish speedy recovery for the injured," El-Sisi said.

"I confirm our determination to continue our efforts to combat dark terrorism and apprehend the culprits," the president added.

At least seven people were killed and seven injured in a terrorist attack Friday on a bus carrying Coptic Christians near the Monastery of Saint Samuel the Confessor in Upper Egypt's Minya, state TV reported, quoting security sources.

Security forces are currently searching for the unknown gunmen who carried out the terror attack on the bus, the sources said.

"This attack will not weaken the will of our nation in continuing its battle to prevail and build," El-Sisi said.
