Occupied Jerusalem: The family of a captured Israeli soldier is setting out on a 12-day march to Jerusalem to press Israeli leaders to make a deal with his Hamas captors to free him.

Sgt. Gilad Schalit was taken captive by Gaza Strip militants four years ago.

His parents say they will camp outside Prime Minister Benjamin Netanyahu's official residence until their 23-year-old son is released.

Schalit's father, Noam Schalit, said before starting the march on Sunday the family "won't wait any longer in our home." He called on the government "to put an end to this sad saga."

Thousands are expected to join the Schalits' march.

Israel is reluctant to free some Palestinian prisoners Hamas wants released because they were involved in deadly attacks on Israelis.
