By Yasmine Ghania and Menna AlaaElDinCAIRO, Aug 2 (Reuters) - President Donald Trump has said the U.S. will hold off on a fresh attack on Iran as long as a deal can be reached quickly to halt Iran's nuclear ambitions and reopen the Strait of Hormuz. "Based on this request, I have agreed, for the future benefit ​of the WORLD and, likewise, the survival of a successful and prosperous Iran, to cancel the attack, subject to being able to rapidly make a DEAL," Trump wrote.

People familiar with the matter had told Reuters the plan included the collection of voluntary fees for using the strait. Trump and Netanyahu met on Tuesday in Washington, with an Israeli official saying they had explored all possible paths to curb Iran's nuclear programme, including diplomacy, economic pressure and force.
