Monasterace, July 8 - A mayor in the Calabrian town of Monasterace who endured repeated death threats resigned Monday. Maria Carmela Lanzetta, a mother of two and a pharmacist by trade, said she resigned when the city council voted not to stand as plaintiff in a mob-related case. She first tendered her resignation then retracted it shortly after someone fired shots at her car one year ago. In June 2011 her pharmacy was burned by arsonists. Lanzetta, who travels with a police escort, said the choice was "painful but necessary" in an open letter to House Speaker Laura Boldrini, who was planning a visit to Monasterace later this week. Lanzetta became mayor in 2003 after the town was dissolved for infiltration by the Calabria-based 'Ndrangheta mafia, believed to be the strongest in Italy due to its hold on the European cocaine trade.
