The Iranian president Hassan Rouhani said on Tuesday that his US counterpart Donald Trump had shown the world he was "not a good partner" by threatening to tear up a 2015 nuclear deal.

"In recent months, the world has witnessed that the US, in addition to its constant and repetitive breaking of its promises in the JCPOA (nuclear deal), has ignored several other global agreements and shown its allies that the US is neither a good partner nor a reliable negotiating party," Hassan Rouhani told parliament.
