Banning Russia from the SWIFT financial system is unlikely to be included in an initial sanctions package in the event of an invasion, a White House official said on Friday, confirming a Reuters report.

"Those closest to Russia, such as Hungary, will be against any sanctions short of a military invasion," according to one senior diplomat.
