Italy: Post WWll - Present

An attack on U.S. and Italian forces in Somalia:

"In the second attack, a bomb blast targeted a peace-keeping envoy from Italy. The Italian Ministry of Defense confirmed that the convoy was hit by explosions, but stated that no injuries had been reported. Images of the attack seen by Newsweek showed that a light-armored vehicle had been sheared open from the attack and extensive damage had been caused to nearby buildings.
No casualties reported except for a Somali civilian."

From Analisidefesa:

"Local media reported the explosion of an improvised device (IED) stating that the Italian convoy was on the Jaale-Siyaad road and had just left the "Green zone" (the protected area that includes the port and airport and houses some ministries , government offices and international bodies presided over by the Somali military) to head to the Somali Ministry of Defense."

The U.S. base that was hit was apparently a drone base for the MQ9 Reaper.
