"The Green Prince"

A senior Hamas leader publicly disowned his son Monday, days after the young man announced he had secretly spied for Israel and helped authorities hunt down members of the Islamic militant group.

Hamas Web sites published a letter late Monday by Sheik Hassan Yousef that the militant group said was smuggled out of the Israeli prison where he is serving a six-year sentence.

In the letter, he said his family announced its “complete renunciation” of Mosab Yousef. The father said he was sorry to take such a step but said he had no choice after his son “disbelieved in God…and collaborated with our enemies,” he said.
