Rockets were fired from Lebanon into Israel sparking concern about whether the fragile ceasefire​ with the militant group would hold.

Israeli artillery and airstrikes hit south Lebanon on Saturday after Israel said it had intercepted rockets fired from across the border, endangering a shaky truce that ended a year-long war between Israel and Lebanese armed group Hezbollah.

Israel has carried out the most intense air strikes on Lebanon in nearly four months, after several rockets were fired from Lebanon into Israel for the first time since a ceasefire came into effect in November.
