US President Donald Trump's administration will reimpose the first batch of Iran sanctions on Monday since Washington withdrew from the 2015 nuclear deal. The more significant tranche of sanctions, including on oil sales, won't however, come into force until November, reports The Hill news.

Trump announced in May that he was withdrawing the US from the 2015 accord with Iran, Germany, France, the UK, Russia and China. The deal, which was negotiated by his predecessor Barack Obama, lifted sanctions on Tehran in exchange for curbs on its nuclear programme.
