Between 9 July and 15 August, the Israeli authorities severely tightened restrictions on the movement of goods through the Kerem Shalom crossing between Gaza and Israel, and further reduced the area permitted for fishing at sea from six/nine to three nautical miles. According to the Israeli authorities, these measures were in response to the launching of incendiary kites and balloons from Gaza into Israel that have resulted in extensive property damage. In May, over the course of the demonstrations, the crossing was set on fire and damaged twice by demonstrators, and closed for a few days on each occasion.
