According to the U Party, the device was detonated at 5:30AM, but did not explode completely. The damage done to the headquarters was minor, and no casualties were reported.
This is the second attack on the same building since Saturday, when a bomb exploded at the entrance of the headquarters with minimal damages and no casualties as well.
Authorities have not attributed the attacks to any organization, but according to Mayor Armando Largo Rivera, the situation of public order is very delicate. Last week armed men bombed a small power plant that left 6,000 people without power in the town.
