An Israeli soldier is missing following a bloody seven-hour battle Sunday in an East Gaza neighborhood, Israel’s military said Tuesday, but it was unknown yet whether the soldier was dead or alive. The development could complicate diplomatic efforts underway to stop the conflict between Israel and Hamas as it enters its third week.

Hamas announced Sunday that it had captured an Israeli soldier. Israel’s ambassador to the United Nations promptly denied the claim, but Israel’s military said it was investigating. The soldier was one of seven Israelis inside an armored personnel carrier in the Shijaiyah enclave when Hamas militants attacked with an antitank missile.

On Tuesday, Lt. Col. Peter Lerner, an Israeli army spokesman, said the military has not been able to identify the soldier’s remains from among those removed from the vehicle.

“We have positively identified six dead soldiers, and we still need to determine if the seventh soldier is missing,” Lerner said.
