Following the blast, gunshots were heard inside the army base as security forces opened fire on the attackers, Hamdullah Danishi, the province’s deputy governor told the Associated Press.
Meanwhile a Taliban spokesman claimed the responsibilty of the attack and death of more than 19 members of the Afghan National Army including 3 top officers.
Also in Afghanistan’s capital, Kabul, militants have attacked a bus filled with army officers, killing at least five.
There were no immediate reports of deaths.
According to the Afghan Defense Ministry, the vehicle was about four miles (seven kilometers) from downtown on Jalalabad Road, when it was ambushed.
Taliban spokesman Zabiullah Mujahid has claimed responsibility for the attack. Further details were not available.
Meanwhile, in southern Afghanistan, another member of the US-led International Security Assistance Force (ISAF) lost his life in a bomb attack on Sunday.
The death brings the total number of foreign troops who have died in the country this year to 700.
2010 has been the deadliest for foreign troops since the US-led invasion back in 2001. This is mainly due to a dramatic increase in Taliban attacks over the past 18 months.
This comes as US President Barack Obama on Thursday unveiled the result of a two-month National Security Council assessment on the war in Afghanistan, claiming that Washington has been “on track” in achieving its objectives in the war-wracked country.
However, as casualties rise in Afghanistan, public support for the prolonged war has begun eroding substantially in the United States and other countries.
A new poll published by ABC News/Washington Post on Thursday shows that some 60 percent of Americans think the war is not worth fighting, up seven points since July.
