Iran launched a serious attack against Israel, coinciding with Israeli troops invading Lebanon. The attack may be an attempt by Iran to counter Israel's expanding actions and alleviate pressure on its ally Hezbollah. Israel has been retaliating against Hezbollah for two weeks, launching about five times as many strikes inside Lebanon. The Israeli military has issued directives for vehicles not to cross the Litani river due to the security situation, and civilians have been urged to leave the area. An estimated million people have already been displaced. The situation has become even more dangerous with the Iranian missile attack.
