ROME (Reuters) - Italy, which is expected to lead a U.N. peacekeeping force in Lebanon, will be unable to send troops if Israel "keeps shooting", Italian Foreign Minister Massimo D'Alema said on Tuesday. "From Israel, we expect a renewed effort, this time truly binding, to respect the ceasefire," D'Alema said. "It's fair to expect that Hizbollah put down their weapons, but we cannot send our troops to Lebanon if the (Israeli) army keeps shooting."
