JERUSALEM (AP) — Israel has vowed to lay total siege to the Gaza Strip, as its pounds the impoverished, Hamas-ruled territory in the wake of an unprecedented weekend incursion. More than two days after Hamas launched its surprise attack from Gaza, the military said Monday that the fighting within Israel had largely died down for now. Israel’s vaunted military and intelligence apparatus was caught completely off guard, bringing heavy battles to its streets for the first time in decades. Israel formally declared war on Sunday, portending greater fighting and a possible ground assault into Gaza. Prime Minister Benjamin Netanyahu vowed to destroy the militants’ “military and governing capabilities.”
