The South Goa district administration swung into action after three mysterious explosions were reported in coastal Canacona taluka here on Thursday.

Deputy collector Deepak Desai confirmed that they had received the report of the explosions and the government machinery was put into action.

The locals stated that three blasts of huge magnitude were heard in the coastal belt of Khola, Agonda and Palolem belt, which forced the administration and police machinery to swing in action.

Policemen in four vans and scores of panchayat level workers were combing the entire area.

Desai said that they have not found any clue and there was no report of any damage.

The district administration also approached the Indian Coast Guard which has begun their aerial surveillance over the area.
