A Palestinian was killed Thursday in a Gaza protest demanding an end to the Israeli blockade, Palestinians reported. Gunshots pierced the air as thousands of Gazans gathered at the Karni cargo crossing and IDF troops fired tear gas to keep the protesters at bay. Dr. Moaiya Hassanain of the Gaza Health Ministry said one person was killed by gunfire and 16 others, including three children, suffered gunshot wounds. The IDF said troops opened fire when demonstrators approached the border fence, believing the movement to be terror related. The soldiers were on high level following the attempted terror attack earlier Thursday morning, in which an Islamic Jihad suicide bomber driving a truck loaded with four tons of explosives tried to ram the Erez crossing. "You will fall, your corrupt state will fall," the crowd chanted at Karni. Some of the protesters climbed electrical poles to hoist Hamas flags, and a song predicting the "Zionists' death" played in the background. "No one can stop the volcano," the lyrics went. IDF tanks rumbled into Gaza from the Israeli side of the passage, and bulldozers leveled farmland in the area so terrorists couldn't hide. Plumes of black smoke climbed into the sky after protesters set tires alight. Separately, a 62-year-old Palestinian civilian was shot and killed in central Gaza on Thursday morning, according to Hassanain. The IDF said it had no soldiers in the vicinity and the circumstances of the man's death remained unclear.
