JERUSALEM - About 14,000 Hamas militants have been killed or arrested in the Israeli onslaught in Gaza, while half of the commanders in the leadership of the military wing were eliminated, the Israeli army said in a statement on Tuesday.

The list of casualties released by the Israeli army includes Marwan Issa, deputy commander of Hamas's Izz ad-Din al-Qassam armed wing, and two of Hamas's five division commanders.

The list does not include Mohammed Deif, the chief of Izz ad-Din al-Qassam armed wing, who was the target of the massive Israeli airstrikes on Saturday, which killed at least 90 Palestinians.

Israeli security officials estimated on Saturday that there is a high probability that Deif was killed in the attack, but Hamas denied it.
