Israeli warplanes have once again struck the southern part of the Gaza Strip overnight, the military says.
Palestinian witnesses and Israeli military sources said Monday that an Israeli aircraft hit a tunnel on the Rafah border with Egypt, AFP reported.
The witnesses said no one was injured in the attack.
The army said the attack came in response to a rocket fire from the Gaza Strip.
The military launched a new series of attacks on the strip as tensions run high over the regime's settlement activities in East Jerusalem (al-Quds).
Its warplanes bombed several sites including a disused airport in southern Gaza Strip late Friday night, leaving more than 14 people injured.
