I just (00.10 Beirut time) heard gunfire coming from the Achrafieh area in east-Beirut. Lasted for around two minutes. At the same time, gunfire reported in Hamra, west-Beirut. This lasted for about ten minutes. Nobody knows what is going on. The UN has 24 hours ago decided to start the Hariri tribunal. So the gunmen might be happy or angry people. All we know for sure, at the moment, is that it were people.
I'm going out now and will check out what actually happened.
