CALLS FOR RESTRAINT
As well as blaming Iran for the tanker attacks, Washington has said Tehran was behind May 14 drone strikes on two Saudi oil-pumping stations. Tehran has denied all those charges.
Britain has backed the United States in blaming Iran for the tanker attacks. On Saturday, Iran summoned the British ambassador to complain about its "unacceptable stance," ISNA news agency reported.
Other nations have urged caution. Germany said the video released by the U.S. military was not enough to prove Iran's role, while U.N. Secretary-General Antonio Guterres called for an independent investigation to determine responsibility.
China and the European Union called for restraint.
Iranian President Hassan Rouhani renewed Iran's threat to continue scaling back compliance with the nuclear deal unless other signatories to the pact show "positive signals".
He did not specify what Iran wanted in his comments to a meeting of Asian leaders in Tajikistan.
France and other European signatories to the nuclear deal have said they wanted to save the accord. But many of their companies have cancelled deals with Tehran, under pressure from the United States.
