Tensions grow as Trump tells Fox News he is considering ‘wiping Iran out’ after attacks on Riyadh by Houthi rebels

Governments across the Middle East are bracing for an escalation of violence after Iran claimed it had received intelligence that the US was preparing for a renewed bombing campaign against the Islamic Republic.

In a potential sign of growing tensions before the UN general assembly in New York this week, Donald Trump cut short a weekend visit to the Camp David presidential retreat on Sunday with no official explanation, and a new security alert was issued by the state department to all US citizens in the Middle East.
