Israeli troops have opened fire at Palestinian houses and destroyed farmlands in Jabalya in the Gaza
region, but there have been no immediate reports of casualties.
About 10 Israeli military tanks and bulldozers entered and attacked the eastern part of Jabalya city late on Saturday, Aljazeera correspondent Hiba Akila reported.
The military vehicles were stationed at al-Hawuz hill, which overlooks Jabalya and Bait Lahia cities, she said.
The Israeli forces and tanks opened heavy and random fire at Palestinian houses in the area for seven hours, Akila added.
They then withdrew early on Sunday to the eastern border, the correspondent reported.
The attack is part of an Israeli operation in Bait Hanun city, which started more than a month ago, she said.
Hundreds of Palestinian families
have been stuck for over a month
The Israeli operation has included a complete closure and destruction of farmlands and houses in Bait Hanun, Akila reported.
Hundreds of Palestinian families have been surrounded and stuck in their houses for more than a month, she said, and humanitarian groups can hardly reach them to supply food.
The Israeli army says its operation is an attempt to prevent Palestinian fighters from firing rockets at Israeli settlements and cities north of and around Gaza city.
Meanwhile, Israeli police has been placed on high alert after receiving warning of possible attacks by Palestinian fighters, Aljazeera's correspondent reported.
The Israeli army has been heavily deployed and has set up checkpoints at the gates of towns and cities in northern Israel and Bisan area in the Jordan Valley, the correspondent added.
