Kabul, Afghanistan (CNN) -- A group of militants Monday attacked Jalalabad airport in eastern Afghanistan, lobbing grenades at the airport's main gate, according to Ahmad Zai Abdulzai, Nangarhar provincial spokesman.
The attack prompted airport security guards to open fire, causing the attackers to scatter, he said.
The fighting has ended, officials said, and a search for the attackers is under way. There are no reports of casualties.
Last year, a group of suicide bombers attacked an area near the airport.
The airport is reportedly used infrequently by United Nations officials.
