“Several parties have talked about the issue of (Syrian) refugees and what struck me were the remarks of (Jumblat's bloc MP Akram) Shehayyeb and (PSP spokesman) Rami al-Rayyes, who spoke in the name of the PSP's feudalism about the 'racism' of Michel Aoun and (caretaker Energy and Water) Minister (Jebran) Bassil,” Aoun told reporters after the weekly meeting of the Change and Reform bloc in Rabiyeh.
