GAZA CITY, Gaza Strip (AP) — Israeli airstrikes killed a senior militant commander in the Gaza Strip and Palestinian militants fired rockets toward Jerusalem on Friday, further escalating the most violent flare-up in months despite efforts to broker a cease-fire. The fighting, which started on Tuesday, between Israel and Islamic Jihad — the second-largest militant group in Gaza after the territory’s Hamas rulers — has killed at least 33 Palestinians in the strip, including women and children, and an 80-year-old woman in central Israel, identified in Israeli media as Inga Avramian. The airstrikes and rockets have shifted the focus of long-running conflict back to Gaza after months of surging violence in the occupied West Bank under Israel’s most right-wing government in history
