Rough cut (No reporter narration). A long-awaited prisoner exchange between Israel and Hamas began as a convoy of buses made their way at dawn on Tuesday (October 18) towards the Kerem Shalom crossing. The first phase of the exchange, expected to take several hours, will end a saga that has gripped Israelis over the five years of the soldier Gilad Shalit's captivity in Gaza. A long and heavily guarded convoy left the Ktsiyot prison in Israel's southern Negev desert where the majority of inmates had been held.
