Then, two days after that robbery, a van loaded with nitroglycerin was robbed in Barcelona, Spain. Those explosives have not been recovered either.
European authorities are worried, to say the least. These are not the unstable homemade munitions used in many recent terrorist attacks, they are military-grade. But precisely who took them, and for whom, remains a mystery.
In the June 28 incident, more than a dozen thieves stormed the military armory of Tancos, located about 80 miles from Lisbon. The Portuguese government, which immediately notified the Ministry of Interior of the neighboring country, Spain, has since convened various national security meetings and launched an investigation the details of which remain carefully guarded secrets.
On Tuesday, July 11, Portuguese Prime Minister António Costa met with senior military officials to analyze the security of the country’s military installations and gather data on what had happened in Tancos. In the subsequent press conference he insisted he felt “calm” based on such information as the military had provided about the theft.
