Former captive IDF soldier Gilad Schalit on Thursday joined the petition calling on President Shimon Peres to increase pressure on the US to release imprisoned Israeli agent Jonathan Pollard. Gilad's parents Noam and Aviva Schalit also signed the petition.
So far nearly 30,000 people have signed the petition, demanding that Peres act on the issue, before receiving the Presidential Medal of Freedom from US President Barack Obama in the summer.
The president's office said they were working hand in hand with the campaign for Pollard's release and that Peres intends do his utmost to bring about the release of Pollard.
"As president, I see it as very important to work determinedly to bring about Jonathan Pollard's release," Peres said a week earlier.
"We are all united in the call to release him immediately. In all my meetings with president Obama and top American government leaders I raised the request to release Pollard and I will continue to do so when I meet with Obama in June."
