Hostage Rescued in Gaza as Israeli Airstrikes Kill Scores of Palestinians

An elite Israeli military unit rescued a frail and gaunt hostage from a tunnel deep beneath the Gaza Strip on Tuesday, the eighth living captive to be freed by Israeli troops in nearly 11 months of war and the first to be found alive in the subterranean labyrinth used by Hamas.

The rescue came amid Israeli airstrikes across Gaza that Palestinian emergency services said killed at least 20 people. At one of the bombing sites in the southern city of Khan Younis, emergency crews frantically searched for survivors trapped under a collapsed building.

The rescued hostage, Farhan al-Qadi, 52, a member of Israel’s Bedouin Arab minority, was freed by commandos without a fight after being discovered in a room roughly 25 yards underground, Israeli officials said. More than 100 hostages remain in Gaza, at least 30 of whom are now presumed dead by the Israeli authorities.

The Israeli military’s chief spokesman, Rear Adm. Daniel Hagari, portrayed the operation to rescue Mr. al-Qadi, as “complex and brave.” He said the soldiers reached him after “precise intelligence” was collected by Israel’s security services.

But that account was at odds with details provided by two senior Israeli officials who spoke on the condition of anonymity in order to discuss a sensitive matter.

Mr. al-Qadi, the Israeli officials said, was found by chance during an operation to capture a Hamas tunnel network. A team led by Flotilla 13, Israel’s equivalent to the U.S. Navy SEALs, were combing the tunnels for signs of Hamas when, to the forces’ surprise, they found Mr. al-Qadi on his own, without guards, the officials said.
