Hours after Israeli police forces clashed with rioting Arab demonstrators at Jerusalem's Temple Mount on Monday, UN Secretary General Ban-Ki Moon called for a stop to 'provocations' at Jerusalem's holy sites. 'I am... deeply concerned by repeated provocations at the holy sites in Jerusalem. These only inflame tensions and must stop,' he said at a joint news conference with Palestinian Authority Prime Minister Rami Hamdallah in Ramallah, AFP reported.
