Trump calls Strait of Hormuz 'something that we don't need'

Israel claims it "dismantled" several targets in western province of Ilam Province, saying they were linked to Iranian security forces and involved in the brutal crackdown of protesters earlier this year, as the IDF said in a statement Tuesday.

Infrastructure for Iran's Internal Security Forces, Basij forces and Islamic Revolutionary Guard Corps was destroyed in Ilam province, the IDF said, adding that they were locations where forces "carried out many terror attacks and brutally repressed internal protests during demonstrations that took place across Iran in the December–January period."

However, Iranian news outlets have reported attacks on “residential buildings” and also some attacks on IRGC-related facilities in Ilam Province over the past few days.

President Donald Trump based his assessment of an imminent Iranian attack on the U.S. on intelligence he had received, White House press secretary Karoline Leavitt told reporters Tuesday.

"Iran chose this path" and Trump "was not going to sit back" and allow this to happen, Leavitt said.

The U.S. military is achieving its objectives faster than anticipated, White House press secretary Karoline Leavitt told reporters Tuesday.

"More than 5,000 enemy targets have been struck so far. Iran's ballistic missile attacks are down more than 90%, and their drone attacks are down by approximately 85% since the start of Operation Epic Fury," Leavitt said.

When asked for a timeline for the end of the military operation, Leavitt said this would be left up to President Donald Trump and would only happen when there is an "unconditional surrender" of the Iranian regime.

Leavitt said the "surrender" announcement won't necessarily come from the regime, but when the U.S. government determines Iran no longer poses a "credible threat" to the U.S.

Since the start of the war with Iran, 140 U.S. service members have been wounded, but a majority of the injuries have been minor, according to the Pentagon.

"Since the start of Operation Epic Fury, approximately 140 U.S. service members have been wounded over 10 days of sustained attacks," Chief Pentagon Spokesman Sean Parnell said in a statement on Tuesday. "The vast majority of these injuries have been minor, and 108 service members have already returned to duty. Eight service members remain listed as severely injured and are receiving the highest level of medical care."
