A Korean unit stationed at Bagram air base in Afghanistan was hit in an artillery attack overnight on Monday (local time).
According to the Defense Ministry on Tuesday, no casualties have been reported, but there was some minor damage to the unit's UH-60 helicopter.
The first four rounds of shelling occurred at around 11:58 p.m. on Monday, and the second round was struck at around 1:30 a.m. Tuesday. The Defense Ministry said there have been a total of 21 artillery attacks on the U.S. air base this year.
The 350-member Ashena unit has been stationed in Afghanistan since June 2010 and is expected to return to Korea at the end of this year.
