Berlin : NATO chief Jens Stoltenberg defended the alliance’s decision to refrain from stepping into the war in Syria, saying doing so would only make matters worse, reports AFP.

All 28 NATO members belong to the US-led coalition battling the Islamic State group but they are not directly involved in the Syrian conflict.

“We are experiencing in Syria a horrible human catastrophe. Sometimes it is right to deploy militarily — such as in Afghanistan,” Stoltenberg told Bild am Sonntag.

“But sometimes the costs of a military operation is higher than its benefit. Looking at Syria, NATO partners came to the conclusion that a military deployment would only make a terrible situation worse,” he said.

“We would risk turning it into a bigger regional conflict. Or more innocent people could die. A military deployment is not always the solution,” he warned.
