Undercover Israeli police officers scuffle with a Palestinian as his son is being detained during clashes in the East Jerusalem neighbourhood of Ras al-Amud October 9, 2009. Palestinian leaders on Thursday called for a general strike over disputed Jerusalem and warned of further protests on the Muslim day of Friday prayers at al-Aqsa mosque. Israel says it is not taking seriously recent Palestinian warnings that a general uprising is about to break out. REUTERS/Baz Ratner (JERUSALEM POLITICS CONFLICT)
