Four people were killed in an explosion on Saturday at a makeshift farm building in Beni Suef governorate in Egypt in what police said was a bomb-making operation gone wrong.Police said that bomb-making materials and machine guns were found in the rubble.
Another person was injured in the explosion, an interior ministry statement said, adding that they belonged to the Muslim Brotherhood group, which was designated a terrorist organisation in 2013 and banned.
Egypt has been hit by a wave of bombings and other militant attacks since the ouster of the Brotherhood's Mohamed Morsi in July 2013. Egyptian authorities have repeatedly linked the group with the violence, but Brotherhood officials have denied any links.
Earlier in April, three people in Sharqiya governorate died when an improvised bomb they were manufacturing accidently exploded.
The deadliest attacks have been centred in the country's restive Sinai Peninsula, where the Egyptian government has been battling a militant Islamist insurgency for the past decade.
Attacks in North Sinai are mostly claimed by the Islamic State-affiliated group, Ansar Beit Al-Maqdis.
Hundreds of police and army personnel have died in the attacks, while hundreds of alleged militants have been also killed by security forces.
