NATO Secretary-General Jens Stoltenberg expressed his sadness over the loss of three NATO force members in the terrorist attack.

"My thoughts are with those who have lost their loved ones, and with the Czech Republic who have lost three military personnel in a suicide attack in eastern #Afghanistan. #NATO stands with the Afghan forces in their fight against terrorism," he tweeted.

Sacrifice on behalf of Afghan people & our coalition will endure in our hearts & history & further strengthen our resolve."
