German police say two drunken youths have been arrested after damaging a memorial to an Egyptian woman stabbed to death last year. Police said the two, aged 18 and 20-years-old, had pushed over one of the memorial's concrete pillars shortly after midnight Thursday, according to AP. They say the suspects considered themselves left-wing and said they were upset that people killed in Afghanistan get little attention whereas the memorial received publicity. A local group dedicated to fighting right-wing extremism, Buerger.Courage, erected the memorial called «18 Stabs» in memory of Marwa al-Sherbini, a 31-year-old pharmacist killed in July 2009 in the city of Dresden by a Russian-born German. It consists of 18 massive concrete pillars _ weighing 1,300 pounds (600 kilogram) each _ depicting knives sliding into the ground in various places in central Dresden. Five of them had been vandalized before Thursday's incident, but police didn't arrest suspects before.
