Adults warring, children paying price

(CNN) - In three weeks of clashes between Israel and Hamas, so many of the victim's faces we've seen are young ones.

The spark for this current fighting can be traced back to June 12th, when three Israeli teenagers were kidnapped in the West Bank and murdered. One of the boys had American citizenship. Then on July 2nd, apparently in retaliation, a Palestinian teenager was burned alive.

Now, as Israel and Hamas trade attacks, it's the Palestinian people - and Palestinian children most tragically - taking the heaviest toll.
