# Train bombing

## About this network

This undirected network contains contacts between suspected terrorists involved in the train bombing of Madrid on March 11, 2004 as reconstructed from newspapers. A node represents a terrorist and an edge between two terrorists shows that there was a contact between the two terroists. The edge weights denote how 'strong' a connection was. This includes friendship and co-participating in training camps or previous attacks.
