International envoy Tony Blair says the US-led Quartet of Mideast mediators is expected to unveil a new strategy for Israeli-Palestinian peace talks in five to six weeks. Blair told Palestinian reporters Wednesday that the plan is being worked on at the highest levels of the Obama administration. He said he doesn't know the details. The Obama administration has promised to work for the establishment of a Palestinian state alongside Israel. President Barack Obama is meeting this month with the Israeli, Palestinian and Egyptian leaders. Blair says that after those meetings, the Quartet is to convene in Washington to discuss and present the new strategy. The Quartet includes the US, the United Nations, the European Union and Russia.
