A flotilla of aid ships bound for the Gaza Strip is preparing to leave Cyprus, organisers say.
Earlier reports said the ships had already set sail around 5am local time (02:00 GMT). But organisers later said they merely relocated to a different location, 40km off the coast of Cyprus, and that the ships haven't actually left for Gaza yet.
"We looked at the little blue bubble this morning and saw that it had moved 25 nautical miles, so we thought they had set off," said Greta Berlin, a member of the Free Gaza Movement, referring to the flotilla's website, which marks the position of the boats with a blue arrow.
Al Jazeera's Mohamed Vall, reporting from the flotilla, said the ships expected to leave for Gaza on Sunday afternoon.
A total of six ships are expected to set sail. Two other ships were damaged over the weekend, and remain in port.
Organisers say they might launch a second smaller flotilla on Tuesday, which would include the two damaged ships, plus a third which has yet to arrive.
"Now we are thinking of sending a second wave of boats including these two and the Rachel Corrie, which is still en route" from Ireland, said Audrey Bomse, an adviser to the Free Gaza Movement.
Hundreds of pro-Palestinian activists are on board the flotilla, which aims to reach Gaza in defiance of an Israeli embargo on the territory. The flotilla was originally made up of nine ships - from Turkey, the UK, Ireland, Greece, Kuwait and Algeria -carrying roughly 10,000 tonnes of aid, including cement, water purification systems and wheelchairs.
It was initially expected that the flotilla would set sail on Saturday, but it was delayed over the weekend due to mechanical problems.
The boats were forced to anchor off the coast of Cyprus this weekend.
Hamas, the de facto rulers of the Gaza Strip, have said that the flotilla was about to make history, sending "a strong message that the blockade imposed on the Gaza Strip ... will be broken".
Israel said the boats were embarking on "an act of provocation" with the Israeli military rather than providing aid, and that it had issued warrants to prohibit their entrance to Gaza.
It asserted that the flotilla would be breaking international law by landing in Gaza, a claim the organisers angrily denied.
Israel has said that it will intercept the boats and detain those on board in the port of Ashdod.
