On Thursday, in Aden city in the south of Yemen, five civilians were killed in a blast in a public market.
An explosive device was placed in a garbage container in a public market in the Sheikh Othman district, northern Aden, a security source told.
20 injured people arrived at the hospital for treatment, adding that some of the injured are in critical condition, a medical source in a hospital in Aden also told.
No group has claimed responsibility for the incident and there has been no comment from the Yemeni authorities on the matter thus far.
As part of its conflict with the Yemeni government, Aden has been under the control of the Southern Transitional Council, backed by the United Arab Emirates, since August 2019.
Since 2014, when Iranian-aligned Houthi rebels captured much of the country, including the capital Sanaa, Yemen has been engulfed by violence and instability.
In early 2015, a Saudi-led coalition entered the war to restore the Yemeni government to power.
With millions suffering from hunger, the eight-year conflict has created one of the worst humanitarian crises in the world.
