Israel’s military ground operation in southern Lebanon has been expanded, the country’s defense minister Israel Katz said on Wednesday. Katz did not clarify when the decision to expand operations was taken and did not offer any details on what the expansion entails.

The conflict between Israel and Hezbollah has deepened in recent days despite diplomatic efforts to move toward a temporary truce.

An Israeli strike on a home in northern Gaza killed three siblings aged 6 and under, among at least six people killed in airstrikes in the war-ravaged territory, Palestinian medics said. In Lebanon, an Israeli airstrike on an apartment building south of Beirut on Wednesday killed at least six people and wounded 15, the Health Ministry said.
