Sixteen members of Morocco's royal guards were killed in a bus accident on Saturday.
The guards were headed north to al-Hoceima for the arrival of King Mohammed VI.
The bus plunged into a ravine near al-Hoceima in the early morning but it remains unclear why it swerved off the road.
Al Hoceima is about 280 miles northeast of the capital, Rabat.
Eight of the guards are said to be in serious condition.
