A suicide bomber detonated his explosives at the gate of the compound at around 9 am local time (10.30 am Indian Standard Time).
An Afghan official told global media, "A group of armed men then entered the compound".
The provincial health department said 11 wounded people had been taken to hospital.
Attackers detonated auto explosives before entering the Save the Children office in the eastern Afghan city Jalalabad.
"I hope for a quick and safe end to this horrific incident", he said on Twitter. The province has become a stronghold for Islamic State, one of Afghanistan's most unsafe militant groups.

Attahullah Khogyani, spokesman for the provincial governor, says the attack today was against Save the Children's provincial office in Jalalabad.
The Taliban released a statement claiming responsibility. By about 10am dozens of Afghan Special Forces descended on the scene.
This comes just days after a 17-hour siege by Taliban insurgents on the Intercontinental Hotel in Kabul, which killed at least 43 people - many of whom were foreigners.
The International Committee of the Red Cross announced in October it would "drastically" reduce its presence in the country after seven employees were killed in attacks a year ago.
Sporadic gunfire is ongoing at the compound as authorities work to contain the situation, according to the latest local reports.
