India's imports from Iran could start to slow from August as some big Indian refiners worry that their access to the US financial system could be cut off if they continue to import Iranian oil, prompting them to reduce oil purchases from Tehran.
According to Bloomberg news agency, which cited two officials familiar with the negotiations, Beijing, however, agreed not to increase purchases of Iran's crude.
A decision by U.S. President Donald Trump in May to back out of the deal means U.S. sanctions will snap back into place later this month and in November.
The three European signatories to the nuclear deal, the United Kingdom, France and Germany agreed with China and Russian Federation last month to continue to support Iran through the reimposition of USA sanctions.
"At 9pm [15:30 GMT on Friday] they attacked the school and tried to break the doors down and burn things", the Fars News Agency quoted the head of the school in the town of Ishtehad, Hojatoleslam Hindiani, as saying.
Trump unilaterally withdrew the U.S. from the multilateral deal with Iran in May and announced plans to reimpose sanctions on the Islamic Republic, that would eliminate Tehran's oil revenues.
Last month, Iran's Supreme Leader Ayatollah Ali Khamenei backed President Hassan Rouhani's suggestion that Iran may block Gulf oil exports if its own exports are stopped. He called Washington's attempt to reduce Iran's oil exports to zero was "mindless" and a sign that the Trump administration has not "thought about its consequences".
Last month, United States officials familiar with the matter said the Trump administration had launched a communications campaign to foment unrest and put pressure on Iran to end its nuclear programme and its support of armed groups. "China will continue to cooperate with Iran adhering to its global obligations", she added.
Currently China is the world's top buyer of crude oil, including from Iran, making Chinese refusal to cooperate a major challenge to the US.
In a statement, Captain Bill Urban, the military's Central Command spokesman, said the U.S. was "aware of an increase" in Iranian naval operations in the Gulf, the Strait of Hormuz and the Gulf of Oman.
