This week is the Malta International Fireworks Festival. You can read more about it on this LINK.
Saturday it moves to Gharb in Gozo - so if you are in the area it would be well worth a visit. This weekend there is also the 2012 edition of Seher il-Punent which is a folk festival held in Gharb every year.
These are the links for some of the events taking place during this event in Gharb this weekend:
There will also be a motorcyle show.
