Joint Chiefs of Staff Chairman Gen. Lee Sun-jin on Tuesday called for a swift military response to any terrorist attack using chemical, biological and radiological weapons.
  

He was inspecting a related exercise in Seoul with the scenario of warding off toxic gas spread by terrorists at an express bus terminal.
  

Soldiers at the Chemical, Biological and Radiological Defense Command participated in the training also involving a chopper and a reconnaissance robot, the Army said.
  

The drill was aimed at checking the military's counter-terror posture amid growing concerns about terrorism, especially since the Paris attack last month, it added.
  

"A series of recent terror attacks were sophisticated and reckless, causing a big loss of lives, and big social and economic damage," Lee said. "In case of terror, it's most important to minimize damage through perfect early countermeasures." (Yonhap)
