Iran continues to hold negotiations with Washington through Qatar and other mediators but remains deeply sceptical of Trump’s intentions, a security source tells Al Jazeera.

“Tehran continues negotiations with the American side through Qatari mediators and others, but it does not have the slightest optimism about Trump’s intentions even for a moment,” the source said.

“We think that there may be different voices in the US, but experience has shown that the US president and his circle are succumbing to the temptations of [Israeli Prime Minister Benjamin] Netanyahu and the warmongering extremists who support him,” the source was quoted as saying.

“For this reason we are obliged to maintain our focus on being fully prepared for a decisive and punitive defence against any aggression and crime by the United States and Israel.”
