Authorities in Yemen have identified a suspect in the killing of a World Food Program official in the southern Taiz province, a security official has told AFP.

Moayad Hameidi, the head of the UN food agency’s office in Taiz, was killed in a shooting Friday in the nearby city of Turbah, the Rome-based WFP has confirmed.

“The perpetrator of the criminal assassination of the United Nations employee in the city of Turbah in Taiz (province)... has been in the city of Taiz since 2017, after fleeing Aden due to security operations against al-Qaeda operatives,” the security official said late Friday.

Speaking on condition of anonymity, the Taiz province official was unable to confirm whether the suspect belonged to the extremist group.

Aden has been the seat of Yemen’s internationally recognized government since the Iran-backed Houthis seized the capital Sanaa in 2014.

The conflict escalated the following year when the Arab Coalition intervened in support of the government.

Fighting has eased over the past year, although sporadic attacks continue.

An arrest warrant has been issued for the suspect, according to an interior ministry telegram seen by AFP.

Taiz is controlled by the government but is surrounded and blockaded by areas under Houthi control.

Al-Qaeda in the Arabian Peninsula and fighters loyal to ISIS have thrived in the chaos of Yemen’s war.

The Arab Coalition as well as the United States and UAE-backed forces have clamped down on extremists in Yemen.

In an initial statement on Friday, the WFP said it was “deeply saddened” by the death of its employee.

The agency later announced that “Moayad Hameidi, a Jordanian national, died shortly after being transferred to hospital.”

He “was shot and killed by unknown gunmen on Friday afternoon in Turbah,” it added.

“A dedicated humanitarian, Hameidi, had worked for WFP for 18 years, including a previous stint in Yemen as well as time in Sudan, Syria, and Iraq.”

WFP’s Yemen country director, Richard Ragan, said: “Any loss of life in humanitarian service is an unacceptable tragedy.”

The UN special envoy for Yemen, Hans Grundberg, said in a tweet: “Our deepest condolences go out to Moayad’s family, friends, and colleagues. And we mourn his tragic loss with the humanitarian community in Yemen.”

In 2018, Lebanese aid worker Hanna Lahoud, who worked for the International Committee of the Red Cross, was killed by unknown assailants in Taiz province.
