Here is the chart for the moment the first gunfire was heard at 8AM on March 22 in Brussels. Depressing.
Notice the packed 12th house of secret enemies, Pluto, the ninja on the MC being trined by the Moon, which is just moving from Jupiter Retrograde (religious fanatics) to the North Node (a moment of destiny). This movement of the Moon triggers the event. Today we have the eclipse, of course.
Also note that Mercury is on 0° Aries, applying to the Sun and trining Mars in Sagittarius — which we could associate with firearms. Fires are started as the messenger reaches Aries.
Also see that Chiron, in his guise as wounder not healer, is on the South Node. The Moon sweeps through these degrees 16-21, bringing together Jupiter, Uranus, Chiron and the Nodes and Pluto during the attack and just before, as the terrorists are preparing.
You can see quite clearly that this is an activation of the Uranus-Pluto square which is sitting on the angles of this chart.
Very, very awful.
