KUSA—Sen. Mark Udall (D-Colorado) directed his ire at Russian President Vladamir Putin in the wake of the downing of Malaysia Airlines flight 17 on Thursday, calling for increased sanctions against Russia.
"The sanctions that we're imposing on Russia need to be strengthened and to be broadened," Udall told 9NEWS. "[Putin] needs to understand this is completely unacceptable if the reports and analysis bear out what we believe right now."
The comments echoed those made earlier in the day by Sen. John McCain (R-Arizona,) who told CNN increased sanctions should be imposed if a Russian connection is proven.
Udall, who sits on the Senate intelligence and armed services committees, also told 9NEWS an international military investigation is needed to determine exactly what happened to the Boeing 777.
US officials say the plane was shot down by a surface-to-air missile over Eastern Ukraine.
The Associated Press is reporting that Putin is saying Ukraine bears responsibility for the downing of the airliner.
