The daily also stated that this is the first time the Iranian government makes a decision like this since it agreed to curb its nuclear activity in 2015 in exchange for the removal of nuclear sanctions.
US President Donald Trump and French counterpart Emmanuel Macron have vowed a strong response to the suspected poison gas attack, which left dozens dead, and the UN Security Council was expected to discuss the crisis later today.
In January, Trump announced he is waiving the USA sanctions against Iran for the "last time".
He added Iran will respond within a week if the USA withdraws from the deal and that Washington will surely regret it.More news: IDF Troops Fire After Gaza Border Breach
"Today, I am waiving the application of certain nuclear sanctions, but only in order to secure our European allies' agreement to fix the awful flaws of the Iran nuclear deal. Our response will be stronger than what they imagine and they would see that within a week", Rouhani said in a speech broadcast live on state television.
Speaking at a conference marking Iran's National Nuclear Technology Day, Rouhani cited what he described as the deal's many benefits for Tehran, including closer cooperation with Russia, China and certain European countries.
Under the 2015 agreement, Iran promised to scale back its nuclear enrichment and give up its pursuit of nuclear weapons.
The government will sell the U.S. dollar at a rate of 42,000 rials to all individuals and businesses, Iran's First Vice President Eshaq Jahangiri said in a statement recorded for state TV and published on its website, adding that enemies of the Islamic Republic and of the government were behind the instability.More news: N.

"We resolutely oppose the use of chemical weapons by any country, any organisation, any person, for any reason, under any circumstances", Chinese foreign ministry spokesman Geng Shuang told reporters during a regular press briefing.
Rouhani also said Iran will launch new facilities in the Fordow enrichment establishments in central Iran.
The rial fell to a record low of 57,000 against the dollar by late afternoon on the unregulated currency market, according to the semiofficial Iranian Students' News Agency.
The US dollar jumped in a day from 54,700 rials to 58,000 rials in the open market in Tehran, local media reported. A dollar was worth 36,000 rials in mid-September.More news: Raikkonen tops Bahrain Grand Prix practice
