The White House accused Iran on Monday of "actively facilitating" attacks on US bases in the Middle East, as it expressed concern over the potential for escalation of the war between Israel and Hamas militants in Gaza. "We know Iran continues to support Hamas and Hezbollah, and we know that Iran is closely monitoring these events and, in some cases, actively facilitating these attacks and spurring on others who may want to exploit the conflict for their own good or for that of Iran," John Kerby said.
