It seems that there has also been some events in other regions of the world such as France and Canada (these are the ones I heard about).
Here are some pictures from the event that took place on July 26, 2008 in Lebanon.
On July 27 1983, five Lebanese Armenains stormed the Turkish Embassy in Lisbon demanding Turkey to acknowledge its 1915 genocide of Armenians.
In a note delivered to the news media during the takeover, the Armenian Revolutionary Army said: “We have decided to blow up this building and remain under the collapse. This is not suicide not an expression of insanity, but rather our sacrifice to the altar of freedom”. The note also said that they had resorted to armed struggle because peaceful means for the ‘pursuit of our just cause’ had failed.
