U.S. envoy Amos Hochstein landed in Beirut on Tuesday for talks with officials on a truce between armed group Hezbollah and Israel, Lebanon's state news agency said, hours after a proposal drafted by Washington won a nod from the Iran-backed group.

Amos Hochstein is expected in Beirut on Tuesday, according to two Lebanese official sources, in a sign of progress in ceasefire negotiations for the deadly cross-border conflict between Israel and Hezbollah in Lebanon.

An Israeli air strike hit a densely-populated neighborhood in the heart of Beirut Sunday evening, killing one person and wounding nine others, according to the Lebanese Health Ministry.
