A year has passed since Hamas launched its brutal attack in Israel, igniting a conflict that had long been brewing but has now erupted into turmoil and tragedy across the Middle East and beyond.

Hamas, which is designated a terrorist organization by the United States and several other nations, killed about 1,200 people and seized more than 200 hostages from inside Israel, according to the Israeli government. Israel's ensuing war in Gaza has killed more than 41,000 Palestinians, wounded more than 97,300, and displaced about 1.9 million, according to Gaza's Health Ministry. The fight has now extended into Lebanon, where Hezbollah, a Shiite Muslim political party and militant group, has fired thousands of rockets into Israel in support of Hamas and Palestinians in Gaza and Israel is responding with air strikes targeting Hezbollah in Lebanon, where the death toll has now reached to more than 2,000, according to Lebanese officials. The war also includes threats from Yemen's Houthi rebels and the possibility of a conflict with Iran.
