According to the agency, "the delicate issue of voting in East Jerusalem" may give Abbas "an excuse to cancel the first elections in 15 years in Palestine."
At the same time, Israel has not yet given an answer whether it will allow a vote in East Jerusalem, but expressed concern about the "growing strength of Hamas."
According to The Times of Israel, Israel's security forces are preparing for possible riots that could erupt if elections in Palestine are delayed.
Elections to the Palestinian Legislative Assembly are slated for May 22, with presidential elections scheduled for July 31.
