Egypt's Foreign Ministry has denounced "in the strongest terms" a suicide attack in Yemen's Aden on Sunday, which killed at least 48 Yemeni soldiers.
The attack, which was claimed by the Islamic State group (IS), is the latest in a string of deadly bomb attacks against recruits in the war-torn country's second city.
Military officials and medics said many others were wounded in the attack that targeted a crowd of servicemen who had gathered to collect their salaries near a base in northeastern Aden.
The attack was carried out by a suicide bomber who blended in among soldiers crowding the house of Colonel Nasser Sarea, the head of special security forces in Aden.
The incident took palce in Al-Arish district, near Al-Sawlaban military base.
Yemeni authorities have been fighting a months-long campaign against jihadists who remain active in the south and east of the impoverished Arabian Peninsula country.
IS group and its militant rival Al-Qaeda have taken advantage of a conflict between the government and Yemen's Houthi rebels, who control the capital Sanaa, to bolster their presence across much of the south.
The Yemen war has killed more than 7,000 people, about half of them civilians.
Egypt is part of a Saudi-led military coalition against Iran's backed Hothi rebels in Yemen since March 2015.
