This picture taken through a wrecked car shows Italian Prime Minister Silvio Berlusconi (C) escorted by the head of the Italian Civil Protection Guido Bertolaso (C-R) as he visits the site where two gas-filled rail tankers exploded after derailing on June 30, 2009 in the seaside resort of Viareggio, northern Italy. At least 16 people were killed and dozens more injured. The explosion happened just before midnight when a wagon in a 14-carriage train transporting liquefied petroleum gas (LPG) came off the rails in the coastal town, which is just northwest of Pisa.
