Israel expanded its bombardment in Lebanon on Saturday, hitting Beirut’s southern suburbs with 12 airstrikes and striking a Palestinian refugee camp deep in northern Lebanon for the first time. The attack on the Beddawi refugee camp near the northern city of Tripoli killed an official with Hamas’s military wing, along with his wife and two young daughters, the Palestinian militant group said in a statement.

Tripoli is much farther north than the majority of Israel’s strikes, which have been concentrated in southern Lebanon and Beirut. Israel has killed several Hamas officials in Lebanon since the Israel-Hamas war began in October last year, in addition to most of the top leadership of Hezbollah. At least six people were killed in more than a dozen Israeli airstrikes overnight and into Saturday, according to National News Agency, Lebanon’s official news agency.
