Israel declared “a state of alert for war” and called up reserves after Hamas militants infiltrated Israeli territory from the Gaza Strip and fired rounds of rockets across Israel, killing at least one person and injuring dozens of others. It’s one of the most serious confrontations in years following weeks of rising tensions along the volatile border. In a rare statement, Hamas military commander Mohammed Deif called on Palestinians inside Israel and Israel’s Arab neighbors to join the fight. Israeli media reported gun battles in neighborhoods in Israeli areas near the border.
