Thousands of people are expected to take part in mass rallies across Spain tonight in protest against ETA. The militant Basque separatist group has been blamed for killing a top anti-terrorism official whose funeral took place this afternoon.The show of solidarity from members of the royal family and politicians across the divide reflected the widespread condemnation of what many have deemed to be an outrage. The victim, 49-year-old police inspector Eduardo Pueyes Garcia was blown up in his car close to the city of Bilbao. A minute of silence was held in his memory in several cities in the Basque region, including Bilbao and San Sebastien. If confirmed, the killing would be ETA’s first fatal attack in six months; and the first since the Socialist Party took control of the Basque regional government, following elections in March.
