BEIRUT: A US envoy is due in Lebanon on Tuesday (Nov 19) for talks on a ceasefire between Israel and Hezbollah , with Beirut positive about Washington's efforts to end the war but seeking changes to a proposal on how to monitor a truce, a senior Lebanese official said. The trip by White House envoy Amos Hochstein, whose visit was flagged by several Lebanese sources but has yet to be confirmed by Washington, is expected to build on a US ceasefire proposal submitted to Lebanon last week .
