Israel and Hezbollah trade accusations of ceasefire violations

The Israeli military said its air force struck a facility used by Hezbollah to store mid-range rockets in southern Lebanon on Thursday, after both sides accused each other of breaching a ceasefire that aims to halt over a year of fighting.

Israel said it also opened fire on Thursday towards what it called "suspects" with vehicles arriving at several areas in the southern zone, saying it was a breach of the truce with Iran-backed armed group Hezbollah, which came into effect on Wednesday.

Hezbollah lawmaker Hassan Fadlallah in turn accused Israel of violating the deal.

"The Israeli enemy is attacking those returning to the border villages," Fadlallah told reporters, adding "there are violations today by Israel, even in this form".

The Lebanese army later accused Israel of violating the ceasefire several times on Wednesday and Thursday.

The exchange of accusations highlighted the fragility of the ceasefire, which was brokered by the United States and France to end the conflict, fought in parallel with the Gaza war. The truce lasts for 60 days in the hope of reaching a permanent cessation of hostilities.

Israel's airstrike on Thursday was the first since the truce took effect on Wednesday morning. Lebanese security sources and the Al Jadeed broadcaster said it took place near Baysariyah, north of the Litani River.

The ceasefire deal stipulates that unauthorized military facilities south of the Litani River should be dismantled, but does not mention military facilities north of the river.

Earlier, Israeli tank fire hit five towns and some agricultural fields in southern Lebanon, state media and Lebanese security sources said, saying at least two people were wounded.

All the areas lie within 2 km (1.2 miles) of the Blue Line demarcating the border between Lebanon and Israel, in an area the Israeli military has announced as a no-go zone along the border, even after the deal was agreed. 

The Israeli military said in a statement it had identified several suspicious activities that posed a threat and breached conditions of the ceasefire agreement.

"Any deviation from this agreement will be enforced with fire," said Chief of the General Staff Herzi Halevi. 

Later on Thursday, Israeli Prime Minister Benjamin Netanyahu said he had directed the military to be prepared for intense fighting if the ceasefire is violated.

"We are enforcing powerfully," Netanyahu said in an interview with Israel's Channel 14. "But if needed I gave a directive to the IDF - be prepared in case there is a violation of the framework of the ceasefire, for an intense war."

Lebanese families displaced from their homes near the southern border have tried to return to check on their properties. But Israeli troops remain stationed within Lebanese territory in towns along the border and Reuters reporters heard surveillance drones flying over parts of southern Lebanon.

The Israeli military on Thursday renewed a curfew restricting the movement of residents of southern Lebanon south of the Litani river between 5 p.m. (1500 GMT) and 7 a.m.
