#MOSCOW (Sputnik) - US intelligence has not detected any divisions within Iran's leadership following the launch of the military operation against the country, The Washington Post reported on Tuesday, citing sources familiar with the matter. Based on US intelligence assessments following the outbreak of war, the Iranian government will remain intact, the report said. There are no clear signs of a split or defections within the Iranian leadership, the report added. US President Donald #Trump receives "very sobering briefings" on US intelligence, and even before he gave the go-ahead for the joint conflict with #Israel, he was informed of the likelihood of a buildup by the Islamic Revolutionary Guard Corps (IRGC), the newspaper reported, citing a source. The US's Arab allies in the Persian Gulf are angry and concerned that they have become the target of Iran's retaliatory strikes, the report added. "They started this war for Israel and then left us to face the attacks by ourselves," an unnamed senior Arab official was quoted by the newspaper as saying. On February 28, the United States and Israel began striking targets in #Iran, including Tehran, causing damage and civilian casualties. Iran is retaliating with strikes on Israeli territory, as well as on US military targets in the Middle East.
