Tensions between Iran and Israel are escalating after recent attacks. Ayatollah Ali Khamenei warned that the U.S. and Israel would face a strong response from Iran. His comments came as the country prepares to mark the 45th anniversary of the U.S. embassy seizure in Tehran. An advisor to Khamenei mentioned that Iran plans to expand the range of its ballistic missiles and might change its nuclear policy. These threats follow an Israeli airstrike on October 26 that killed four Iranian soldiers, which was in retaliation for missile attacks from Iran on October 1. The ongoing conflict involves Iran`s support for groups like Hamas and Hezbollah, which have been attacking Israel. Israel holds Iran responsible for backing these groups, especially after significant attacks that resulted in many casualties last year.
