Iranian Foreign Minister Javad Zarif shot back via Twitter saying "Iran's launch of space vehicles — & missile tests — are NOT in violation of Res 2231," which is the UN resolution which endorsed the Joint Comprehensive Plan of Action (JCPA) on Iran's nuclear program — which the Trump administration pulled out of last May.
FM Zarif wrote on Thursday in response to Pompeo while warning "threats engender threats" and linking to the UN text:
Iran's launch of space vehicles — & missile tests — are NOT in violation of Res 2231. The US is in material breach of same, & as such it is in no position to lecture anyone on it. Reminder to the US: 1. Res 1929 is dead; 2. threats engender threats, while civility begets civility.
Iran's defense ministry previously announced plans for three Space Launch Vehicle (SLV) launches in "the coming months," according to an official statement. This after in late November Iranian Deputy Defense Minister General Qassem Taqizadeh first unveiled plans to send three Iranian made satellites into space soon.
"The satellites have been made by domestic experts and will be put on various orbits," Taqizadeh said.
