Two electricity pylons in the Nile Delta were hit by blasts on Sunday night, injuring six people and cutting off power supplies, state news agency MENA reported.
Unknown assailants targeted two high-pressure electricity pylons with six bombs in Beheira governorate’s Al-Nobareya city.
Power lines fell on the road as a result of the blast, bringing traffic to a halt and cutting off electricity to the city.
Authorities arrived at the site and defused another bomb. They also put a security cordon in place.
Egypt has seen a number of attacks on electricity pylons and other economic targets recently. On Sunday, pylons were hit in southern Egypt near the High Dam.
Earlier in April, attackers brought down two electricity pylons near the media city in Sixth of October City on the outskirts of Giza, cutting power and putting channels off air. Electricity pylons feeding factories in 10th of Ramadan City in Sharqiya governorate were also targeted in March.
Egypt has suffered from power crises for several years, with power cuts recurrent throughout the summers. The president has said the country needs large investments to renovate its power networks.
Egyptian cities have witnessed a wave of bomb attacks and drive-by shootings, mainly targeting police and army personnel, since the ouster of Islamist president Mohamed Morsi in July 2013. Civilians have been also been affected.
Anti-government Islamist militant groups have claimed responsibility for a number of attacks, particularly in North Sinai where the army has been facing a decade-long jihadist insurgency that has intensified over the past year and half.
