Israel's 2,000-pound SPICE bombs are highly accurate but could be overkill in Gaza

• Israeli forces have been using SPICE kits to convert unguided bombs into precision munitions.
• Even though they kits are highly accurate, there's still potential for lots of collateral damage.
• Weapons investigators say the large bombs dropped have wide area effects and can harm civilians.

Israel's bombing campaign of the Gaza Strip is back on following accusations last week that Hamas violated the fragile truce between the two warring sides, and in the days since, visual evidence has emerged showing the use of massive, 2,000-pound SPICE bombs in densely populated areas.
