Turkey : The US Senate passed a bill on Monday that could be used to block or slow the transfer of the F35 advanced warplane to Turkey, a NATO ally that has an increasingly strained relationship with Washington.
There have been bipartisan efforts in both the Senate and the House of Representatives, to potentially stop the transfer to Turkey.
The National Defense Authorization Act (NDAA) now needs to be reconciled with a bill from the House of Representatives and could be approved by the end of the summer.
The Senate version of the act is worth about $716bn.
Both houses have introduced their own version of amendments that target Turkey – one of the partner countries on the F35 programme.
