A homemade explosive device went off in a cinema in the eastern Congolese city of Butembo on Monday, wounding at least 10 people, including children and teenagers, an army official and a hospital worker said, APA reports citing Reuters.
It was not immediately clear who was behind the attack, which security forces are investigating, said local army spokesperson Anthony Mwalushayi, who gave a provisional report of three injured.
An employee at a local university clinic, Mbayahi Nathan, said the facility received 10 injured people after the explosion.
"They were between 10 and 21 years old," he said, adding that one patient's injuries were life-threatening.
Butembo, a trading hub of almost 1 million people, is sometimes the target of Islamic State-linked militants known as the Allied Democratic Forces (ADF).
An improvised bomb that detonated outside the national intelligence agency's Butembo office last month, wounding two agents, was suspected to be an ADF attack, according to local police.
