Similarly, a majority of 54% supported the killing of the three kidnapped Israelis and 42% opposed it. Support for the killing reached 69% in the Gaza Strip and only 42% in the West Bank. 52% of the West Bankers opposed the killing of the three kidnapped Israelis.

The public is divided over the identity of those who carried out the kidnapping and the killing of the three Israelis: 32% accuse Israel, 30% accuse Hamas, 21% believe a Palestinian acted on his own, and 2% accuse Fatah.”
