An Israeli demonstrator shouts slogans behind a cardboard cut-out of captured Israeli soldier Gilad Shalit during a protest calling for his release outside Prime Minister Benjamin Netanyahu's office in Jerusalem February 5, 2010. A senior Hamas leader said earlier this week indirect talks with Israel on a prisoner exchange had collapsed and blamed Netanyahu for hardening Israeli terms.
