America proposed a 48-hour ceasefire through one of its friendly countries on April 13th, according to Fars citing an unformed source - UNCONFIRMED AND DATE IS IN THE FUTURE, SO TREAT WITH CAUTION

Evaluations indicate that this proposal was made after the crisis in the region escalated and serious problems arose for the American military forces due to the incorrect estimation of the military power of Iran. According to this report, Iran's response to this proposal was not given in writing, but with a field response and continued heavy attacks.
