A powerful car bomb exploded at Madrid's international airport, wounding 26 people in an attack blamed on the Basque separatist group ETA and bringing a nine-month long cease-fire to an abrupt end.
The Spanish government announced it was suspending plans for negotiations with ETA after the bombing on Saturday. Two people were still missing hours after the explosion.
"As the conditions that we laid down have not come about, I have ordered the suspension of all initiatives to develop a dialogue," Prime Minister Jose Luis Rodriguez Zapatero said. "The government considers that today's attack is incompatible with a permanent cease-fire."
"Today's action is the most mistaken and useless step the terrorists could have taken" said Zapatero.
