The purpose of the project was to raise awareness of the dire situation of the hostages who have been held captive by Hamas for over seven months.

Mourners yelled out at Prime Minister Benjamin Netanyahu as he spoke at a ceremony on Jerusalem's Mount Herzl, and one man flew an Israeli flag that said "7.10" on it as he spoke.

"Without the hostages there is no Independence," said organizers who invited the public to join them watching the ceremony's live stream from home or from screenings around the country.
