'I am ashamed of what we are doing in Gaza,' says ex-chief of Israeli security agency

Ami Ayalon says his desire to end the war in Gaza is both professional and personal.

Ayalon — the former head of Shin Bet, Israel's internal security agency — has signed an open letter on behalf of 550 former Israeli security officials calling for an end to Israel's military campaign in the besieged Palestinian enclave. 

Speaking on behalf of the signatories, Ayalon says Israel long ago achieved its stated military goal of dismantling Hamas, and must now strike a deal to bring its remaining hostages home.
