At least two Afghan security officers were killed and 10 other people, including soldiers and civilians, were injured in the eastern province of Nangarhar, officials said on December 2.
The two killed were intelligence service members and one was director of the Jalalabad intelligence department, said Attahullah Khogyani, spokesman for the provincial governor.
The attack took place when a rocket was fired toward a private TV station in Jalalabad, followed by a blast as security arrived at the scene, followed by a third explosion.
An Islamic State group affiliate claimed responsibility for the attack.
In another incident, a magnetic bomb attached to an Afghan army recruiting booth exploded in Kabul, injuring at least three people.
No group claimed responsibility for this attack.
Magnetic bombs are part of a new tactic to target Afghan government officials.
