The death toll has risen to at least 190 after a series of bombs placed on rush hour trains in Madrid Thursday. More than 1,200 are injured. The Spanish government blamed Basque separatists for what is being called the worst terrorist attack in its history. But there are other signs that suggest al-Qaida and its supporters may be responsible.
   Ambulances carry the dead and wounded from some of Madrid’s busiest train stations. As ninny as 10 bombs exploded in the city in what appear to be closely coordinated terrorist attacks.
   Addressing the nation, Spanish Prime Minister Jose Maria Aznar called it mass murder, blaming the Basque separatist group ETA and vowing to track down those responsible for what British Foreign Secretary Jack Straw calls a shocking, unbelievable outrage.
   "This is, without any question, at least the worst terrorist outrage, which has taken place within Europe since the Lockerbie bombings at the end of the 1980s,’ he said.
