Shots were also fired at a person guarding the Athens Appeal Court building, Justice Minister Stavros Kontonis told state TV. The Justice Ministry suspended the court s operation for one day. There were no reports of injuries. Two Greek media organizations received warning calls at 2:50 a.m. (0050 GMT), before the explosion, one official said.  Police, who had cordoned off the area, later found a bag which contained the makeshift bomb outside the building. Police were also investigating footage from cameras nearby, another official said, and reports of two people leaving the scene in a van. Small-scale attacks on businesses, state buildings, police and politicians are frequent in Greece, which has a long history of political violence.  Public anger remains high after seven years of belt-tightening in a crisis that has cut thousands of jobs and eroded living standards Protesters have repeatedly tried to block foreclosure auctions of home at courts, a key condition of Greece s international bailout. Electronic auctions started in November.
