The speaker of Iran's parliament, Ali Larijani, has warned the West that his country will build nuclear plants if the implementation of the nuclear deal is delayed.
"You would either lift the sanctions, according to the deal, and avoid threatening behavior against the Iranian nation or fail to fulfill your promises, and if the latter is the case, the (Iranian) nation's response will be harsh," he threatened.
On that day, President Barack Obama signed an order directing his administration to begin issuing waivers to Iran nuclear sanctions, though the waivers will only go into effect once Iran meets its obligations under the agreement.
Iran's Supreme Leader Ayatollah Ali Khamenei last month said  Tehran would not negotiate with the United States on any issue after the landmark nuclear deal with the six world powers in July, and has also repeatedly referred to American the "Great Satan"  and presided over chants of "Death to America."
