US Secretary of State Mike Pompeo announced on Monday that the US government "will initiate a review of the scope of our cooperation with Afghanistan" and cut $1 billion in aid, effective immediately, due to the leadership impasse between Afghan President Ashraf Ghani and his political rival Abdullah Abdullah.

The announcement came after Pompeo made unannounced visits to Kabul, Afghanistan and Doha, Qatar to meet with key officials amid efforts to broker a peace deal for Afghanistan.
