Gaza gunmen killed 18 alleged spies for Israel on Friday, including seven who were lined up behind a mosque with bags over their heads and shot in front of hundreds of people. The killings came in response to Israel's deadly airstrike against three top Hamas military commanders.
The killings occurred after more than six weeks of heavy fighting between Israel and Hamas. In new violence, a 4-year-old Israeli boy was killed by Palestinian rocket fire, while four Palestinians were killed in Israeli airstrikes in Gaza.
