Taliban insurgents attacked a U.S. base in Afghanistan on Monday, an assault which U.S. authorities called "unsuccessful," according to Voice of America.

The U.S. base, located near Afghanistan's border with Pakistan, was barraged by suicide bombers who also set fire to military vehicles near their parking lot. Al Jazeera reported that more than 30 vehicles were set of fire or damaged.

All three suicide bombers were killed in the attack.

Ahmad Zia Abdulzai, a provincial governor spokesperson, said three suicide bombers started firing at officials guarding the base, leading to a fight that lasted three hours. He also said that NATO helicopters helped U.S. officials battle the insurgents.

NATO said that none of their officials were killed and local authorities also reported no military or civilian casualties.

Zabiullah Mujahid, the Afghan Taliban spokesman, claimed responsibility for the attack while he was located near a highway often traveled by NATO trucks. Following his claim, the highway was temporarily shut down.

Within the past week, the Taliban has killed more than 100 people after staging attacks across Afghanistan.

The NATO supply line has become under attack from Taliban fighters on both sides of Afghanistan's border, making the organization change their delivery routes.

Just last week, Afghanistan President Hamid Karzai visited Pakistan to discuss the release of Taliban members from jail.

The Afghan military mission will be cancelled by NATO by the end of next year, in addition to troops from all over the world slowly being reduced. Afghan authorities say the reduction of troops and end of NATO is not a concern considering there are 350,000 newly trained troops, which the government believes will be able to handle security concerns after 2014.
