Iran’s chief negotiator Mohammad Bagher Ghalibaf said that talks with the United States would remain bound by Tehran’s “red lines,” AFP reports.

“As we have shown in the past path of negotiations, we are steadfast in fulfilling the conditions and red lines set, and in achieving the interests of the Iranian nation,” Ghalibaf said in remarks published by the official IRNA news agency.

“If the enemy seeks to be excessive, we have proven that our fingers are on the trigger and we have no hesitation in giving a crushing response to the enemy.”
