Hundreds of thousands of people marched through Spain's capital, Madrid, calling for peace in the wake of a car bombing that killed two people and derailed a peace process with Basque separatists.
A sea of people filled Madrid's main north-south artery, with protesters waving signs with a white dove and wearing stickers reading "peace." Rallies were also held in the Basque city of Bilbao and other towns.
The Dec. 30 attack at Madrid's airport came nine months after the Basque rebel group ETA declared a cease-fire. The separatists insist that the truce still stands, but the government canceled plans to negotiate.
