Palestinian and international activists on Tuesday removed parts of a security fence the Israeli army has installed along its borders with the Gaza Strip, witnesses said.

The incident took place during a demonstration organized by humanitarian and social activists against the enforcement of a 300- meter wide buffer zone along Gaza's northern and eastern borders with Israel.

Tens of people, including some international campaigners and farmers, participated in the rally which started from the border town of Beit Hanoun and headed towards the Israeli fence, waving Palestinian flags.

The Israeli army called more troops but did not use force to disperse the demonstrators when they were removing the barbed wires surrounding some lands owned by farmers.

On Thursday, a UN report said that farmers in Gaza have been totally or partially prevented from accessing land located up to 1, 000 to 1,500 meters from the fence. "The land restricted area is estimated at 17 percent of the total land mass of the Gaza Strip and 35 percent of its agricultural land," said the report.
