Last week's truce between Israel and Hezbollah in Lebanon gave renewed impetus to negotiations for a Gaza ceasefire. But in Lebanon, people had not even had time to bury those killed in the past two months before the ceasefire started looking shaky,

Both sides have accused each other of violating the deal; Hezbollah fired into Israel for the first time since the truce took effect, and Israel responded with airstrikes.

Hezbollah has claimed the first strike against Israel since a US-backed cease-fire plan came into effect less than a week ago, prompting Israeli officials to vow a strong response in the most serious threat so far to the truce with Lebanon.
