MNA � In his twitter account on Friday, Iran�s foreign ministry spokesperson Abbas Mousavi reacted to the US withdrawal from Open Skies Treaty.

�The American�s unilateralism & exit from Intl. agreements are still ongoing,� wrote Mousavi.

�In the past 3.5 years, the US Administration had kept breaching its Intl. obligations in entirety & challenging all Intl. norms, rules, and laws which will definitely end up anarchism,� he added.

Washington announced on Thursday that it would withdraw from the 35-nation Open Skies Treaty, allowing unarmed surveillance flights over signatory states, the Trump administration�s latest move to pull the country out of yet another major global landmark accord.

The accord, signed in 1992 and in force since 2002, allows its signatories to conduct short-notice unarmed surveillance flights to gather information on each other�s military forces and installations, thereby contributing to inspections of conventional arms control and strategic offensive weapons and reducing the risk of conflict.
