A patrol spotted the rebels as they laid the explosives at the Girishk dam in restive Helmand province and they were arrested after an hour-long exchange of fire, ministry spokesman Mohammed Zahir Azimi told AFP.
“Twenty Taleban were arrested today by joint Afghan and coalition forces as they were placing bombs to blow up the dam in Girishk district,” Azimi said, without giving further details.
Officials said the dam was no longer producing power.
