Egyptian media say seven Palestinians deported by Egyptian authorities have arrived in the Gaza Strip.
The Palestinians were detained a few days ago at an airport in Cairo for security reasons, after arriving on a flight from Syria.
After an investigation showed no illegal activity, authorities released the Palestinians and began extradition procedures.
In recent weeks, Egyptian authorities have been destroying smuggling tunnels along the Egypt-Gaza border. The tunnels are used to bring fuel, food and construction materials into the territory, and to sneak in weapons and militants.
The Gaza Strip is largely under an Israeli-Egyptian blockade.
