Israel-Gaza live updates: Israel says it killed top militant in West Bank operation

The IDF overnight widened a major military operation in the northern part of the West Bank, attacking from the air and from the ground using tanks and bulldozers, ABC News has learned.

The targets of the raid are Jenin, Tulkarm and Tubas. The IDF has described the ongoing operation as an “extensive operation to counter terrorism” and to “thwart Islamic-Iranian terrorist infrastructures.”

Reports indicate that nine Palestinians have so far been killed, though that number could rise. The IDF has reportedly ordered Palestinians to evacuate from the three targets locations, with troops also entering a hospital in the area.

The raid is believed to be the first operation by the IDF targeting several cities at once since the Second Intifada, which ran from 2000 to 2005.

Israel Defense Forces said it launched an "operation to counter terrorism" in the northern West Bank overnight Tuesday.

"The security forces have now begun an operation to counter terrorism in Jenin and Tulkarm in the Menashe division," the IDF said in a statement.

Qaid Farhan Alkadi, the hostage rescued from a tunnel in Gaza, is in "good condition," but will remain in the hospital for "another day or two of medical tests to make sure he is still OK," Shlomi Codish, the CEO of Soroka Medical Center, said during a press conference Tuesday.

Alkadi is being treated at the Soroka Medical Center after being rescued by Israeli forces.

"He underwent initial evaluation in our emergency department. He appears to be in general good condition, but will require another day or two of medical tests to make sure he is still OK. We are ecstatic with his family. Watching him unite with his children, his brothers, was a heartwarming moment for all of us and we hope to be able to experience such moments with many more returned captives here at Soroka Medical Center," Codish said, according to Reuters.

A delegation from Israel -- including Israeli Security Agency, Mossad and IDF officials -- is heading to Doha, Qatar, on Wednesday to continue hostage release and cease-fire talks, an Israeli official told ABC News Tuesday.
