Two Syrian intelligence officers are giving evidence in Vienna again to the UN commission investigating the murder of Rafiq al-Hariri, the former Lebanese prime minister. The two officials are Syria's former head of intelligence in Lebanon, Rustom Ghazale, and his deputy, retired colonel Samih Kashaami, both of whom were heard by the commission in December. "I think it has begun," Syria's ambassador in Austria, Safwan Ghanem, told AFP, adding he did not expect the hearings to last beyond Monday. The December hearings involved three other Syrians: Abdelkarim Abbas, head of intelligence in Palestine, Zaher Yussef, head of communications and Jameh Jameh, another of Ghazale's deputies. The commission, led since last week by Belgian prosecutor Serge Brammertz, also wants to speak to Syrian President Bashar al-Assad and Foreign Minister Farouk Al-Shareh.
