Israeli naval forces fired warning shots at a Malaysian aid ship as it approached the Gaza Strip yesterday, forcing the vessel to retreat to Egypt, organisers and the Israeli military said.

“The MV Finch, carrying sewage pipes to Gaza, had ­warning shots fired at it by Israeli forces in the Palestinian security zone this morning at 6.54 a.m.” said Shamsul Azhar from the ­Perdana Global Peace Foundation.

“The vessel was in the Palestinian security zone, about 400 metres from the Gaza shoreline, when they were intercepted by Israeli naval forces,” he said, adding it was now anchored 30 nautical miles away in Egyptian territory.

An Israeli army spokesman confirmed that the vessel, flying a Moldovan flag, had been intercepted as it sailed from Egypt’s El-Arish port, where it had been docked for several days.

“A navy patrol boat contacted the vessel, which claimed to be heading for the Gaza shores. Once it crossed into Israeli naval territory and didn’t answer calls to turn back, warning shots were fired in the air and it returned to El-Arish,” she said.

The Perdana Foundation is helmed by former Malaysian premier Mahathir Mohamad, an 85-year-old firebrand who was a strident critic of the West and Israel over the treatment of Palestinians during his two decades in power.

The organisation was also involved in the first “Freedom Flotilla,” a May 2010 attempt to break the Israeli blockade on Gaza, which ended in disaster when naval commandos raided the aid ships, killing nine Turks on board one of the vessels.

Perdana Foundation officials said the MV Finch left Greece on May 11, carrying plastic pipes to help restore the “devastated” sewage system in Gaza.

Alang Bendahara, a Malaysian journalist on board, said that Israeli naval ships fired a volley of gunfire to stop the vessel as it approached the shore.

“The Israeli naval vessel fired a warning shot at us upon approaching and asked us to leave the waters but the ship’s captain refused and the Israelis fired again, circling the MV Finch before firing twice more,” he said.

“At that point they threatened the ship’s captain that they would board the vessel and we were forced to turn back, it was lucky that no one was injured.” Mr Bendahara said Egyptian officials monitoring the boat had escorted it back to Egyptian waters and then boarded it to inspect its cargo.
