GENEVA, June 5 (Reuters) - The United Nations on Friday said it is doubling the amount of money it says it needs to help Lebanon meet surging humanitarian needs, as the war enters its fourth month.
Lebanon was drawn into the wider regional war in early March when the Tehran-backed Hezbollah militia fired rockets at Israel in solidarity with Iran, which was under U.S.-Israeli attack, prompting a major Israeli air and ground campaign.
