The U.S. military has launched a second round of airstrikes targeting Iran at President Donald Trump's direction.
Law enforcement agencies across the Delaware Valley are boosting security at religious and cultural sites following U.S.-Israeli strikes against Iran, even as officials say there is no credible threat to the area.
Iran has vowed revenge after the killing of its supreme leader.
Ayatollah Ali Khamenei, 86, the supreme leader of Iran, was killed in the U.S.-Israeli attack on the country Saturday, President Donald Trump said.
The attacks came a day after Trump voiced frustration over lack of progress in negotiations to stop Iran's ability to develop nuclear weapons.
President Donald Trump vowed "certain death" to the Iranian regime as the U.S. launches a "massive" military operation.
