The political gathering took place in downtown Antananarivo around noon local time. Rajoelina announced the creation of a new transitional government, with himself as its leader, in spite of the fact that the current government is still in place. He asked his supporters to march to the presidential Palace in Ambohitsorohitra.
When the massive crowd arrived at the palace, a delegation entered the palace at 14:46 local time. This is when shots were fired. The local twittersphere and other bloggers reported:
Preliminary reports indicate that dozens of bodies are laying on the streets. Among the casualties, is said to be a cameraman from the RTA TV station (official confirmation still pending).
As of 15:40 local time, shots were still being fired. Rajoelina asked the armed EMMONAT forces, a military entity accepted by both parties and created during the crisis, to intervene and protect the crowds.
