Madrid–Barajas Airport is bombed.

Adolfo Suárez Madrid–Barajas Airport is the main international airport serving Madrid, the capital of Spain, and its metropolitan area. At 3,050 ha in area, it is the second-largest airport in Europe by physical size behind Paris Charles de Gaulle Airport. In 2019, 61.8 million passengers travelled through Madrid–Barajas, making it the country's busiest airport as well as Europe's fifth-busiest.

On 30 December 2006, 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.
