TEL AVIV, Israel – Rocket attacks from Lebanon into northern Israel killed four foreign workers and three Israelis on Thursday, Israeli doctors said, the deadliest cross-border attacks on Israel since it invaded Lebanon. Israel continued airstrikes it says targeted Hezbollah militants across Lebanon, where health authorities on Thursday reported 24 people dead.

American diplomats were in the region pushing for a ceasefire in both Lebanon and Gaza, hoping to end wars in the Middle East as the Biden administration enters its final months. Pressure has been building ahead of next week’s US elections.

In northern Gaza, Israeli forces attacked one of the last functioning hospitals, the World Health Organization said, destroying much-needed supplies the U.N. agency had delivered to the facilities. The attacks caused a fire that engulfed the dialysis unit, destroyed water tanks, damaged the surgery building and injured four doctors who were trying to extinguish the fire, hospital director Dr. Hussam Abu Safiya said.

The Israeli military did not respond to a request for comment about an attack on the hospital, which it stormed last week after alleging it was housing Hamas militants. The Gaza Health Ministry on Thursday condemned the Israeli attacks on the hospital and called on the international community to safeguard medical facilities in Gaza.

Back-to-back deadly rocket attacks hit Israel

Shells from Lebanon hit an agricultural area in Metula, Israel’s northernmost city, killing four foreign workers and an Israeli farmer, local officials said Thursday.

Hours later, the Israeli military reported another volley of about 25 rockets from Lebanon, which hit an olive grove in a suburb of the northern Israeli port city of Haifa. That attack killed a man in his 30s and a woman in her 60s and wounded two others, said Magen David Adom, Israel’s main emergency medical organization.

Both Hezbollah and Hamas are backed by Iran, Israel’s regional adversary. Hezbollah did not immediately claim responsibility for Thursday’s rocket fire. Israel’s military said 90 projectiles were fired from Lebanon on Thursday.
