Israel suffered the most catastrophic assault in its history when Hamas terrorists killed more than 1,000 people and took hundreds of others hostage. Almost a year later, Israel assassinated Hassan Nasrallah,

The attack comes after decades of mutual hostility and a long-running shadow war of covert strikes and sabotage.

Israeli troops entered southwestern Syria in the early hours of Thursday and arrested several people who the Israeli military said were members of Palestinian militant group Hamas but which Syria's interior ministry said were civilians.

But as law enforcement investigates the violent incidents -- from the New Orleans truck rampage to the Molotov cocktail attack in Boulder -- some counterterrorism experts say they're worried the federal government has taken its eye "off the ball" in preventing terrorism as its priorities shift -- from counterterrorism to mass deportation.

The Israeli military recovered the body of de facto Hamas leader Mohammed Sinwar in a tunnel underneath the European Hospital in southern Gaza, the Israel Defense Forces (IDF) said Sunday.

Israel's leader says arming "clans in Gaza" to help fight Hamas will save lives. Opposition leaders say the weapons "will eventually be turned against" Israelis.

The Palestinian Islamist group Hamas said Iran, its strategic ally, was "paying the price" for supporting militant groups in Gaza in their decades-long struggle against Israel, after Israel launched large-scale attacks on Friday against Iran.

Israel is arming local militias in Gaza in an effort to counter Hamas in the besieged enclave, officials say, as opposition politicians warned that the move endangers national security.
