MADRID, October 8. /TASS/. US Secretary of State Marco Rubio believes that the risk of escalation of the conflict in Ukraine may push the nations to negotiate a settlement.

"I think and I hope that the risk of escalation is one of the things that will bring both sides to the table and willing to negotiate a settlement to this war," he said at a press conference in Lisbon, where he is on a visit.

Rubio previously noted that there is a risk of escalation of the conflict in Ukraine and its degenerating into "a much broader and far more dangerous regional conflict.".
