Greek police Saturday arrested suspects allegedly linked to the terror cell plotting the murder of police officers that was uncovered in Belgium Thursday. One of them matches the description of Abdelhamid Abaaoud, a 27-year old Brussels resident of Moroccan origin believed to be the ringleader of the jihadi cell of Verviers. This is not confirmed. Greek authorities are reported to have sent DNA samples to their Belgian colleagues for further investigation. The Greek police said the names of several people had been passed to them in connection with the plot to check if they were in Greece.
