The military showed Times journalists a shaft that it said was evidence of a Hamas facility under Al-Shifa Hospital, though it was unclear where it led or how deep it was.
Sally Abed, a Palestinian citizen of Israel, and Alon-Lee Green, a Jewish Israeli, found polarization in America over the war in Gaza. They also found longing for a new approach.
Israeli officials say the hospital complex hosts major Hamas facilities, some in underground bunkers, a claim that Hamas and hospital officials reject.
The move is an apparent violation of a recent agreement that says citizens from the United States and Israel can travel to the other nation without a visa.
The Israeli military said it had recovered the body of a hostage kidnapped in the Oct. 7 Hamas attack, from a building near Al-Shifa Hospital. It presented weapons it said it found at the hospital, which it says Hamas used as a base.
While the conflict over the breakaway region of Nagorno-Karabakh concluded with an Azerbaijani victory, resentments simmer on both sides, creating fertile ground for new violence.
