US exits Open Skies Treaty
The US said on Sunday that it officially withdrew from the Open Skies Treaty.
"Today marks six months since the US submitted our notice of withdrawal from the Treaty on Open Skies," National Security Adviser Robert O'Brien said in a tweet.
The Trump administration submitted the notice of its decision to withdraw from the treaty in May, and the Sunday announcement marked the end of a six-month notification process.
The treaty, which became effective in 2002, allows its 34 State Parties to conduct short-notice, unarmed reconnaissance flights over the others' entire territories to collect data on military forces and activities.
By 2019, over 1,500 Open Skies flights have been conducted since the deal entered into force, according to media reports.
