Israeli troops have far greater firepower. But elusive Hamas militants are hiding and will seek to ambush Israelis from tunnels that crisscross Gaza.

As Israeli troops advance through Gaza, their target is elusive and dangerous: The Hamas tunnels. The underground network includes military headquarters, sleeping areas and workshops to make rockets.

Israeli airstrikes have leveled apartment buildings in a refugee camp near Gaza City, while evacuees from northern Gaza wait for a chance to pass through the Rafah crossing into Egypt.

Israel bombed the largest refugee camp in Gaza and said it killed a senior Hamas commander. Palestinians said it caused a huge number of civilian casualties.

Thousands of Gaza residents broke into warehouses and distribution centers of the United Nations Palestinian refugee agency, grabbing flour and "basic survival items," the organization said on Sunday.

Israeli troops who fought against Hamas on Oct. 7 prepare for the next battle.

All signs point toward a massive Israeli ground invasion of Gaza as the humanitarian crisis in the coastal territory grows more dire.

As the blame continues on who's responsible for a deadly attack on a Gaza City hospital. President Biden has weighed in. He says he believes it was an errant missile by a Palestinian faction.

The origins of the blast that killed hundreds of people at the al-Ahli Hospital in Gaza are unclear. Israelis and Palestinians are trading blame.

In his visit to Israel, President Biden made a deal on limited humanitarian aid delivery to Gaza. Twelve days ago, Hamas killed 1,400 people in Israel. More than 3,400 people have been killed in Gaza.

The Rafah border crossing is a modest, isolated outpost at the southern end of the Gaza Strip. Yet it could be a critical lifeline as Gazans face a growing humanitarian crisis.

Israel is massing a huge military force just outside the Gaza Strip for what is expected to be a major ground invasion. It has tried and failed in the past to eliminate Hamas' military capabilities.

The latest eruption of Mideast violence is a fight between Israel and Hamas. But the U.S., Iran and Egypt are among the many countries with a major stake in the outcome.

Israel and Hamas are waging one of their deadliest clashes as the U.S. moves naval forces into the Mediterranean Sea. Questions persist about why Israel was caught so unprepared in the assault.

Israeli intelligence has been tracking Hamas closely for years. Why was the group able to plan and carry out such widespread and deadly attacks?

The U.S. has given $75 billion to Ukraine since the Russian invasion. A growing number of Republicans in Congress oppose giving more. That could impede the country's defenses against Russia.

Biden has assured allies Congress will eventually provide more Ukraine funding. But then House Speaker Kevin McCarthy was ousted, making the path forward murkier.

Gen. C.Q. Brown is poised to become the top U.S. military officer in a few days. One challenge he faces was on full display this week: Ukraine's visiting president requested more military assistance.

Gen. Brown has had a four-decade military career, serving as a combat pilot and chief of the Air Force. He was confirmed as chairman of the joint chiefs by a Senate vote of 83-11.

Ukraine needs to make more advances against Russia before winter weather makes conditions more difficult.
