Eighth-grader Dvir Musai, who was wounded on Tuesday on his way back from a school cherry-picking trip in a field near Hevron, is \"in better condition, but still needs much heavenly mercies.\" So said his father today, after his son was operated on in a Jerusalem hospital. Dvir (ben Chanah Dvorah), who is still in the intensive care unit, is suffering from severe wounds to his legs and lower back area. \"We ask that anyone who can should recite prayers and Psalms on Dvir\'s behalf,\" his father said. Two other boys - Evyatar ben Dvorah and Elyashiv Eliyahu ben Hadassah - were also injured in the blast, which was set off when one of the boys stepped on the small gas canister filled with metal and glass pieces. They are suffering from burns and other wounds, and though they are out of intensive care, there is no word yet on when they will be released from the hospital.
