Scary. If this is where I think it is it's not uncommon to see fairly peaceful Arab Spring type protesters in the area as well.
Scary indeed, a few years ago we had actually visited the Bardo museum in Tunis, while on holiday in Yasmine Hammamet.
UPDATE: 19 Killed in Attack at Tunisia Museum; 2 Gunmen Dead After Firefight CAIRO — Gunmen in military uniforms attacked an art museum in downtown Tunis around noon on Wednesday, killing 19 people, officials said. Security forces later advanced into the museum and killed two gunmen in a firefight, state television reported. Prime Minister Habib Essid said at a news conference that the dead included 17 foreign tourists and two Tunisians. State television reported that a Tunisian museum guard who was injured in the attack died later of his wounds. Tunisian authorities said at midafternoon that the operation to retake the museum was continuing and was nearly complete. Local media reports said it was possible a third gunman was involved in the attack and was still at large. State television reported earlier that 10 tourists were being held hostage by the gunmen, including Italians and Asians, but an Interior Ministry spokesman said all had been killed. As many as 15 people were said to have been injured in the attack. http://www.nytimes.com/2015/03/19/world/africa/gunmen-attack-tunis-bardo-national-museum.html?_r=0
