No one was injured in the series of 21 blasts which started on Friday night with 13 bomb attacks on second homes and one on a car.
No-one has so far claimed responsibility for the explosions which were mainly in the island’s southern region, but the letters FLNC, Corsican National Liberation Front, were scrawled on a building near one of the attacks.
On Saturday, three explosive devices were placed under a house in Pietrosella and a further two blasts damaged two homes in Giuncheto.
Two more blasts targeted a villa in the town of Furiani and another in Sagone on Sunday.
Most of the properties targeted were near the coastline, in contradiction of a law which prevents buildings being closer than 100 metres to the shore.
Explosions of this magnitude in Corsica have not been seen since the 1980s-1990s when, during the ‘famous nights of horror’, dozens of blasts could be heard overnight on the island.
On 19 August, 1982, there were 118 explosions during the space of a few hours.
After months of relative calm, questions are being asked as to why the attacks have restarted. Some sources say it is to mark the 36th anniversary of the creation of the FLNC.
Other claim the timing of the blasts, just days after the presidential election, is aimed at putting the ‘Corsican question’ back on the political agenda.
The FLNC wants the island to be an independent state.
