A Obama aide believes his wife had been targeted by an Israeli intelligence firm seeking to "dig up dirt" on officials involved in the Iran nuclear deal, he wrote on Twitter Sunday.
The UK's ambassador to the United States Sir Kim Darroch said the Iran agreement was "a good deal" but efforts were ongoing to "find some language, produce some action that meets the president's concerns".
Though Israel is not interested in an escalation with Iran, if the war with the Islamic Republic imminent, Prime Minister Benjamin Netanyahu would prefer that it happened now and not in the future, while the Jewish state has a military advantage.
Trump and his Middle East allies, particularly Israel, argue the agreement was too weak and must be replaced with a more permanent arrangement and supplemented by controls on Iran's missile programme.
Netanyahu also dismissed experts who said the documents just proved why a deal was necessary.
The official said Trump shared Israel's scepticism about the deal and voiced hope for new US sanctions, noting the effect of past measures against Iran's banking and oil sector.
Britain's Johnson will on Monday begin a two-day visit to Washington, with the nuclear deal among issues on top of the agenda, the Foreign Office said.
One Vienna-based diplomat who has dealt with the IAEA for years, when asked what he made of Netanyahu's speech, said: "Nothing new".
In order for an event to be zero-waste, at least 90 percent of waste needs to be diverted from landfills.
This increasing pressure from multiple sources will make it difficult for Iran to maintain its position that internal policies are not influenced by outside actors, as the pressure for defensive measures increases.
Exchange shop windows that once showed rates for Iranian rial to U.S. dollar transactions have gone blank, as black-market rates have skyrocketed to 70,000 rials to the dollar, far higher than the newly government-imposed rate of 42,000 for $1.
He warned in veiled terms that Iran could consider restarting its now largely mothballed nuclear energy program, which is under inspection of the International Atomic Energy Agency.
Last week, Israel revealed "secret nuclear files" which it said showed Iran had run a clandestine nuclear weapons programme before 2003, and had secretly retained the technological know-how, in breach of the agreement.
Darroch also said that Trump and British Prime Minister Theresa May spoke Saturday about the Iran deal and that the president said "a final decision hasn't yet been taken".
Rouhani added that there would be no negotiations on limiting Iran's missile power or regional influence.
"Of course we are looking at all eventualities. It should never have been concluded". Israel has neither confirmed nor denied involvement.
The comments came as Israel pushed its case to have the deal changed or eliminated, arguing intelligence documents it recently unveiled on Iran's alleged nuclear ambitions helped demonstrate why.
