The New York Times (TEL AVIV) 

The Israeli military said on Saturday that it had struck several Hezbollah sites in Lebanon, keeping the country on edge over a fragile ceasefire, as its forces pressed on with their campaign in the Gaza Strip with little sign of letting up.

The ceasefire in Lebanon forged this past week ended months of destructive airstrikes and fighting, but it is still not clear when all the roughly 1 million people displaced from their homes will be permitted to safely return. Under the deal, Israeli forces are to gradually withdraw from southern Lebanon over 60 days, as Hezbollah fighters also retreat north of the Litani River.

The Israeli military said it hit a site at the Lebanon-Syria border that was "actively being used” by Hezbollah to transport weapons to Lebanon from Syria, in what it called a violation of the ceasefire agreement.

It also said it struck three other sites in southern Lebanon where it had observed militants either "approaching Hezbollah structures,” loading vehicles with weapons or engaging in "terrorist activity” at a Hezbollah facility. It declined to provide further details about any of those strikes.

Hezbollah did not immediately comment on the strikes. Israel has struck at least two other sites that it described as Hezbollah infrastructure since the ceasefire went into effect Wednesday.
