43 soldiers were killed following a blast caused by a suicide bomber in the southern Yemeni port city of Aden on Sunday, officials there said. At least 60 other troops were wounded, they added.
This incident came a week after an attack by the militant ISIS group killed 50 troops nearby.
The troops were queuing to collect salaries near a military base in the Khor Maksar district when the suicide bomber blew himself up, according to officials.
Al Qaeda and ISIS have exploited nearly two years of war in the impoverished country to carry out terror acts.
ISIS claimed responsibility for the suicide bombing and identified the bomber as Abu Hashem al-Radfani.
