The Government is building an anchorage for patrol boats on its Gaza sea border, further bolstering its defences against suspected weapons smuggling by Palestinians, security sources said on Friday. One of the sources told Reuters that the anchorage at Rafah, a town that straddles Gaza Strip and Egypt would be 10 metres deep and 25 metres long. Egypt is already constructing an underground barrier to cut off smuggling through tunnels in the area. "The new anchorage will enhance the work of the Egyptian patrol boats on the sea border with Gaza and prevent any attempts of smuggling by sea," another security source in North Sinai said. The first source said the anchorage was to ensure Palestinian fishing boats, which they suspect of carrying out the smuggling operations, do not come near Egypt's or Israel's coasts. "It is to secure the area. It will be used to direct fishing boats in the area to ensure they do not cross the Israeli sea border and risk getting fired at," he said. Large blocks have been moved to border post 1, the start of Egypt's border with Gaza, where the anchorage will be built. Egypt is also building more watch towers along the border with Gaza to boost sea surveillance, security sources said.
