“Egypt stresses its full support to the sisterly Hashemite Kingdom of Jordan in this painful incident,” the Egyptian Ministry of Foreign Affairs said in a statement late Wednesday, expressing Egypt’s strong condemnation of the attack.

The terrorist attack near the town of Kidal in northern Mali wounded four Jordanian peacekeepers, one of whom died from his wounds, according to the UN. The convoy remained under the attackers’ sustained fire for about an hour.

The attack is the fifth of its kind in the Kidal region in just one week, according to the UN Multidimensional Integrated Stabilization Mission in Mali (MINUSMA). The country has been fighting an extremist insurgency over the past decade.

The UN said the attack was carried out by members of a suspected terrorist group using rocket launchers and other arms.

In March, MINUSMA said more than 250 peacekeepers had died in the west African country since 2013 as the mission has remained under a “daily threat.”

With more than 18,000 personnel, MINUSMA is one of the UN’s largest peacekeeping missions worldwide out of 12 operations with a total of 90,000 peacekeepers.
