A Hamas member was arrested by IDF troops after trying to infiltrate Israel from Gaza at the Karni crossing on Sunday, the IDF said.According to a statement released by the army, the suspect was caught damaging the fence and trying to break through it under the cover of fog. He was transferred to security forces for questioning."This is another terror activity, through which the terrorist organization Hamas seeks to penetrate Israeli territory and harm its citizens," read the IDF Spokesperson's Unit statement. "This is part of the mobilization led by the Hamas terrorist organization in which it tries to equate its terrorist efforts with a civilian cover and turn the fence into a combat zone. The IDF is determined to act and fulfill its obligation to protect the citizens of Israel and not to allow harm to the security infrastructures that protect them."Thousands Gazans have been demonstrating on the border fence with Israel each Friday over the past five weeks ahead of “Nakba Day” on May 15th and the army believes that Hamas uses these weekly demonstrations as cover to carry out terror attacks.On Friday the IDF said that it had thwarted an attempted infiltration at the old Karni crossing in north-eastern Gaza by “hundreds of rioters” who tried to burn the fence and enter Israel. The crowd, it said, had thrown explosive devices, firebombs and rocks leading troops to open fire “in accordance to the rules of engagement” to stop the rioters.While the security establishment does not believe that Hamas currently seeks another conflict, the situation is fragile, especially given the worsening conditions in the Strip.
