Washington, July 09, 2019, SPA -- US President Donald Trump issued today a new warning to Iran, calling on it to be very cautious. "Iran is doing a lot of bad things and it has to be very careful," Trump told reporters at the White House in response to a question about Iran's failure to comply with some of its obligations under the international agreement on its nuclear program. It is worth mentioning that the Iranian regime announced yesterday that it will increase the rate of uranium enrichment to at least 4.5%, while the agreement signed in Vienna in 2015 sets the rate of 3.67% as a ceiling for the enrichment. --SPA 22:00 LOCAL TIME 19:00 GMT 0022 www.spa.gov.sa/w1134332
