(AP) – U.S. Defense Secretary Pete Hegseth said Tuesday will be the most intense day yet of U.S. strikes inside Iran as the Islamic Republic, its firepower diminished, vowed to fight on. Israeli Prime Minister Benjamin Netanyahu meanwhile said “we are breaking their bones” and said the war’s aim is a popular overthrow of Iran’s government.

“Our aim is to bring the Iranian people to cast off the yoke of tyranny, ultimately it depends on them,” Netanyahu said.

U.S. President Donald Trump, for his part, sent contradictory signals about how long the war could last, causing wild swings Monday in financial and fuel markets.

Iranian Parliament Speaker Mohammad Bagher Qalibaf dismissed any suggestion Tehran has sought a ceasefire.
