An Israeli air strike late Friday demolished the house of a suspected Palestinian weapons dealer near the Gaza-Egypt border, the Israeli army and Palestinian police said.
The two-story house was brought down in back-to-back strikes, Palestinian security officials said. The army said the house had covered the entrance to a smuggling tunnel.
There were no reports of injuries. The army routinely notifies owners of homes being targeted in air strikes to give residents a chance of leave.
Later, Palestinian eyewitnesses reported that IDF tanks entered the northern Gaza Stip early Saturday, according to Army Radio.
An army spokesman said troops were conducting a routine operation in the area of Beit Hanun to prevent the launching of rockets into the western Negev.
There were no reports of fighting following the incursion.
