Richard Arnold: US Correspondent on the United States' plans to retaliate against the drone strikes in Jordan

The United States says it'll take all necessary actions to defend itself, its interests, and its people in the middle east.   It comes after three US soldiers were killed in a drone strike in Jordan, near the Syrian border.   The US has blamed an Iranian-backed militia group.   CBS says officials have told them the US has approved plans for a series of strikes on Iranian targets in Syria and Iraq.   US correspondent Richard Arnold told Mike Hosking that they're still finalising plans, and it's expected there'll be a series of strikes over a number of days including on Iranian personnel and facilities inside Iraq and Syria.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
