Madrid–Barajas Airport is bombed.

The 2006 Madrid–Barajas Airport bombing occurred on 30 December 2006 when a van bomb exploded in the Terminal 4 parking area at the Madrid–Barajas Airport in Spain, killing two and injuring 52. On 9 January 2007, the Basque nationalist and separatist organisation ETA claimed responsibility for the attack. The attack, one of the most powerful carried out by ETA, damaged the airport terminal and destroyed the entire parking structure. The bombing ended a nine-month ceasefire declared by the armed organisation and prompted the government to halt plans for negotiations with the organisation. Despite the attack, ETA claimed that the ceasefire was still in place and regretted the death of civilians. The organisation eventually announced the end of the ceasefire in June 2007.

Ordered and planned by then head of commandos Miguel Garikoitz Aspiazu Rubina alias Txeroki, the attack was carried out by the “commando Elurra”, whose members were arrested in early 2008 and sentenced for the attack in May 2010. Txeroki was arrested in November 2008 and is awaiting trial for the bombing.
