June 10 (Reuters) - The UN human rights office will deploy a team of investigators to Lebanon next week to assess potential violations of international law by all parties during the current war in the country, UN human rights chief Volker Türk said on Wednesday. Lebanon was drawn into the wider Middle East conflict on March 2 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.
