"Seven military servicemen were killed" when a "suicide terrorist" blew up a truck loaded with explosives outside a Georgian military base in Afghanistan's Helmand province, General Irakli Dzneladze, chief of the Georgian army joint staff, told a news conference.
The incident brings to 30 the death toll of Georgian soldiers serving in the International Security Assistance Force in Afghanistan (ISAF).
On May 13, three Georgian soldiers were killed in a similar suicide attack on their base in southern Afghanistan.
"Our duty to their memory is to continue our path towards NATO membership," he said.
