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.

The recent attacks are seen as part of Israel’s strategy to force Hezbollah and Lebanon to agree to a ceasefire, and an indication that it is prepared to expand its offensive by killing non-military members of the group and striking places outside areas where the movement has a strong presence, possibly to stir anti-Hezbollah sentiment.

Israeli troops are understood to have made their deepest incursion into southern Lebanese territory since the recent offensive began on October 1, as the militant group Hezbollah considered its response to a fresh ceasefire proposal.
