AL QUDS - For the Palestinian National Authority (PNA) the "provocative" flag march held yesterday by settler groups in the eastern part of Al-Quds (occupied Jerusalem) "will only lead to tensions"."The calls of the extremists to storm the Al-Aqsa mosque (the Esplanade of the Mosques, ed) by storm will inflame the region with disastrous consequences".This was stated by Nabil Abu Rudeinah, spokesman for Mahmud Abbas' (Abu Mazen) PNA, quoted by Wafa. The spokesman also stressed that the Palestinians "hold the occupation regime fully responsible for this escalation which will lead to an explosion of the situation".Then he asked the United States to take a "clear and frank position on these Israeli provocations."
