Daesh has established a stronghold in the province bordering Pakistan, where it fights both the Taliban and Afghan government forces.
As the attack unfolded, heavy gunfire could be heard from around the building of RTA, Afghanistan's national broadcaster, located close to the governor's compound in the provincial capital, Jalalabad, Reuters reported.
Daesh members "are currently carrying out an attack inside the state broadcasting building in the city of Jalalabad," the group's AMAQ news agency said in a statement on instant messaging service Telegram.
The Taliban terrorists, which also has a strong presence in the region, denied responsibility.
Two of the attackers blew themselves up at the start of the operation but a third engaged security forces in a heavy gun battle before being killed, said Attaullah Khughyani, a spokesman for the provincial governor.
Nine of the 17 wounded were discharged from a hospital after being treated, he added.
Daesh has recently been hit hard by US airstrikes and special forces operations.
The head of Daesh in Afghanistan, Abdul Hassib, was reported this month to have been killed in a joint Afghan-US operation in Nangarhar at the end of April.
Daesh has also claimed responsibility for a series of high-profile attacks in the capital, Kabul, including one in March on Afghanistan's largest military hospital.
