Two were killed and four injured following a bomb explosion close to Kafr Al-Sheikh stadium, according to Health Ministry spokesman Hossam Abdel Ghaffar.
The explosion targeted a vehicle carrying army cadets, leaving several of them amongst the casualties.
Military and security personnel have been targeted by militant groups in Egypt since the ouster of former president Mohamed Morsi in July 2013.
On Tuesday, eight Improvised Explosive Devices (IED s) were placed under two electricity pylons in 6th of October City. The pylons provided power supplies to the Egyptian Media Production City (EMPC), with the explosion temporarily cutting off electricity.
