A series of bombings struck restaurants and public squares on Monday in the eastern Afghan city of Jalalabad, wounding at least 66 people, officials said, as the country marked the 100th anniversary of its independence.
No group claimed responsibility for the 10 bombs but both Daesh and the Taliban militants operate in the area.
Daesh claimed responsibility for a weekend bomb attack on a wedding reception in the capital, Kabul, that killed 63 people and wounded nearly 200.
The Jalalabad bombs were planted near a market where hundreds of people had congregated after attending Independence Day events. Senior health official Fahim Bashari said at least 66 people were wounded, including 20 children enjoying the public holiday.
