Iran has condemned the terrorists in Syria for using chemical weapons against the Syrian people and government.

During a speech at the Munich Security Conference, Iranian Foreign Minister Mohammad Javad Zarif said that the use of chemical weapons can never be condoned.

“The use of chemical weapons can never be condoned... Unfortunately the terrorist organizations Nusra and Daesh (ISIS) still possess chemical weapons,” Zarif said.

The Syrian government has said that anti-government militants have been using chemical weapons against civilians. However, the enemies of Bashar al-Assad, the Syrian president, accuse the Syrian government of using chemical weapons.

Zarif also denounced the new US administration for putting pressure on Iran, saying that Iran is “unmoved by threats” but responds well to respect.

Donald Trump, the new president of the United States has repeatedly criticized the nuclear deal between Iran and six world powers, calling it the worst deal ever made.

Trump administration has recently put Iran “on notice” over its ballistic missile test, and imposed new sanctions on some Iranian companies and individuals.

The Iranian foreign minister mocked the concept of crippling sanctions as he spoke at the conference on Sunday morning.

“Iran doesn't respond well to threats. We don't respond well to coercion. We don't respond well to sanctions, but we respond very well to mutual respect. We respond very well to arrangements to reach mutually acceptable scenarios,” he said.
