The Israeli military said on Monday its troops had completely surrounded a key town in southern Lebanon after killing more than 100 Hezbollah fighters there over the past week.

The U.S. military said it would begin a blockade of all Iranian ports Monday, after talks between the warring sides in Pakistan collapsed, and despite the Iranian military warning that it would treat any such action as an act of piracy.
