The local Union of Agricultural Work Committees said in a statement that the fishermen, identified as brothers Safwat and Ra’fat Zayed, were targeted while fishing two nautical miles away from the coast of al-Sudaniya area in Gaza City on Saturday morning.
The statement added that Israeli forces arrested the pair, before seizing their fishing equipment and taking them to an unknown location.
There was no comment from the Israeli military on the arrest, Presstv reported, Presstv reported.
According to Palestinian estimates, roughly 50,000 Gazans earn their living from fishing.
Israel imposed a limit of three nautical miles on fishing in the waters off the Gaza shore until August 2014, when Palestinian fishermen were allowed to go out six miles under a ceasefire agreement reached between the Israelis and Palestinians following a deadly 50-day Israeli war in the same month.
The fishing zone is supposed to extend to 20 nautical miles under the Oslo Accords. The Oslo Accords were signed between the Israeli regime and the Palestine Liberation Organization (PLO) during the early-mid 1990s to resolve the Israeli-Palestinian conflict.
In May 2017, Israeli authorities increased the fishing area for Gazan fishermen to nine nautical miles.
Over the past few years, Israeli forces have carried out more than a hundred attacks on Palestinian boats, arresting dozens of fishermen and confiscating several boats.
The Gaza Strip has been under an Israeli blockade since June 2007. The blockade has caused a decline in the standard of living as well as unprecedented levels of unemployment and unrelenting poverty.
