Obama is trying to show careful attention to both sides and prod direct talks between Israelis and Palestinians.According to WAFA, Abbas spokesman Nabil Abu Rudeina said the Palestinian president emphasized his intent to engage in a "serious and continuous peace process that would lead to ending the Israeli occupation of the Palestinian territory in 1967, as well as the establishment of a Palestinian independent state." On Friday, Chief Palestinian negotiator Saeb Erekat accused Israel of pressuring the Palestinians into joining direct talks without meeting the basic condition for moving forward, freezing the expansion of the settlements, Army Radio reported."The manner of the talks is not important, just their content. The keys are in Netanyahu's hands. The talks will continue the moment he agrees to freeze building in the settlements," said Erekat.
