Palestinians have attended Friday prayers in mosques reduced to rubble by Israeli airstrikes. This collection of pictures show the result of a near month-long air campaign focused on Gaza City, a conflict that has claimed more than 1,900 Palestinian lives, many civilian, including women and children. On Friday, cross-border attacks were resumed after Gaza militants reprised rocket attacks on Israel. Hostilities returned after a three-day cease-fire, brokered by Egypt, ended after talks on ending the blockade of Gaza stalled. Israel hit back on Friday with a series of airstrikes, one that, according to AP, killed a 10-year-old boy.
