RAMAT GAN, Israel — Andrey Kozlov woke up on the morning of June 8 preparing to endure another day in Hamas captivity. But by the afternoon, he had been whisked out of Gaza, rescued by undercover Israeli commandos after eight months of war.

       “Andrey! You’re going with me!” an Israeli soldier shouted as he entered the apartment in the Nuseirat refugee camp where Kozlov was held.
