Israeli sources say four more soldiers have been killed, and 26 others injured during military ground operations in Gaza. The military earlier confirmed that 18 soldiers were killed in the conflict. Meanwhile, reports say an Israeli army jeep has been destroyed by Palestinian fighters as they've launched an operation against Israeli forces in Gaza. Also, Palestinian fighters continue to fire retaliatory rockets into Israel. Four people have been injured as rockets hit Sderot today. The fighters have also targeted Ashkelon and Yad Mordechai. Meantime, Al-Qassam Brigades, the military wing of the Palestinian resistance movement Hamas, says it's captured an Israeli soldier, identified as Shaul Aaron. But Israel denies this.
