The attackers, who were riding a vehicle, opened fire on the checkpoint and later escaped, the sources said, adding the area was cordoned off.
Many terrorist attacks that targeted police and military personnel took place in different parts of Egypt since the January 2011 revolution that toppled the ex-president Hosni Mubarak.
The attacks even increased after the ouster of Islamist ex-president Mohamed Morsi in 2013 following massive protests against his rule.
Over 700 security personnel have been reported killed since then.
