Mahmoud Abbas, the Palestinian president, signaled Monday that he was ready to start indirect peace talks with Israel. Mr. Abbas, left, told Israeli television that he would present the American proposal for talks to the Arab League this week, and “we hope that the reply will be positive.” The talks were derailed last month after Israel announced a new housing development in East Jerusalem, which the Palestinians want as their capital. Jerusalem officials have said the government has effectively frozen new Jewish construction in East Jerusalem.
