Palestine authorities on Monday said that the coastal conclave of Rafah was under missile attack from Israeli warplanes.
The Israeli Army also confirmed that they had hit Hamas targets in the Gaza Strip after Palestinians had fired a rocket into southern Israel.
The Israeli Army, according to GeoTV, said: "fighter jets targeted underground infrastructure in the southern Gaza Strip, in response to the projectile that was launched at Israel earlier."
No casualties were reported in either incident.
The strikes followed fierce exchanges over the weekend in which Israeli ground forces killed two Palestinian teenagers in the enclave in cross-border fire.
Warplanes also pounded 18 Hamas facilities in two waves of air strikes, according to the Israeli military.
