HAMAS WARNS AGAINST GROUND ATTACKS

The Hamas leader-in-exile, Khaled Meshaal, has warned Israel that it would face a "black destiny" if it launched a ground offensive on Gaza.
"If you commit a foolish act by raiding Gaza, who knows, we may have a second or a third or a fourth Shalit," Meshal said, referring to Israeli soldier Gilad Shalit, who was abducted by Gaza militants more than two years ago. "
Speaking publicly for the first time since Israeli air strikes started a week ago, he said Hamas resistance and infrastructure were intact.
His remarks came as the UN warned of a worsening humanitarian crisis in Gaza. The UN said it believed 25% of more than 400 Palestinians said killed by Israeli action so far were civilians.
In a pre-recorded statement broadcast on al-Jazeera TV, Damascus-based Khaled Meshaal, said Israel would be making a "foolish mistake" if it sent tanks into Gaza. "We will not break, we will not surrender or give in to your conditions," Mr Meshaal said in a speech aimed at the Israelis, the Palestinians and the wider Muslim world.

To them, Mr Meshaal said this was not a battle against Hamas alone, but against the entire umma, or nation - analysts say an apparent reference to a populist Islamist idea that the Palestinians are defending the Muslim world against a modern form of Crusades.
The UN said the Israeli military escalated its offensive against the Hamas leadership in Gaza on Friday, targeting the homes of more than 20 Hamas officials in its latest air strikes.
In response, Palestinian militants fired on Israel, launching more than 60 missiles in 24 hours, injuring four people in the southern city of Ashkelon.
