A commemorative ceremony was held in Ansan, South Korea on Sunday to mark the third anniversary of a ferry accident that killed more than 300 people.

Survivors and the families of the victims took part in the event at a group memorial altar, along with major presidential candidates.

Two weeks ago, the wreck of the ferry was finally raised and arrived at a port in Mokpo.

The Sewol ferry sank off the country's southwestern coast on 16 April 2014, killing 304 people, most of whom were students on a high school trip.

The incident touched off an outpouring of national grief and soul searching about long-ignored public safety and regulatory failures.

"Even in the process of salvaging Sewol ferry and investigating the hull, the government and the oceans and fisheries ministry still hold and wield power. The central government is still forcing us to stay still. Families of the victims who had to send away 304 victims and the nation's people who watched live the Sewol Ferry accident cannot stay still. We have to bring back the victims who have not returned yet, and start a thorough investigation (on the accident)."

The families of some of the victims in the Sewol ferry disaster protested at South Korea's Mokpo port on Saturday, as work began to search the wreckage for the remains of the last nine victims of the 2014 sinking.

Most of the 304 people who died when the Sewol sank on April 16, 2014 were teenagers on a school trip.

The protesting relatives were criticising the government's decision to exclude victims' families from the investigation, demanding they be allowed to find out why their children died.

The wreck was raised from the sea floor last week, and was brought to the port on Friday.

"Regarding the way to remove the mud: because the remains (of undiscovered victims) will be very fragile, we are removing mud by hand. We have not decided whether we will be taking the mud out in bags straight from the ferry, or taking them out after keeping them on the semi-submersible vessel for a while."

The corroding 6,800-ton ferry raised from the bottom of the sea off South Korea last week was approaching Mokpo port on Friday, where it will be searched for the remains of nine missing passengers from the 2014 sinking that killed 304.

Finding the remains of the missing victims would bring a measure of closure to one of the country's deadliest disasters.

Most of those who died when the Sewol sank on April 16, 2014, were teenagers on a school trip, triggering a national outpouring of grief and outrage over what were seen as poor rescue efforts by the government.

The anger contributed to the ousting of President Park Geun-hye, who earlier on Friday was arrested over allegations of corruption.

Once the Sewol arrives at port, it is expected to take several days for workers to disconnect it from the transport vessel, where it had been welded in place in order to maintain balance during the trip, and further empty it of water and fuel.

The ferry will then be moved to a dry dock where workers are expected to spend weeks cleaning it and evaluating it for safety.

Investigators will then begin searching for the remains of the missing victims and for clues that could further explain the cause of the sinking, which has been blamed on excessive cargo, improper storage and other issues.

The wreck of the South Korean ferry that sunk in 2014, killing 304 people, was transported to port on Friday after weather conditions improved.

Workers completed the massive operation to lift the corroding 6,800-ton Sewol from the seabed late last week.

They loaded the ferry on a heavy lift transport vessel, emptied the wreckage of water and fuel and removed buoyancy equipment to enable it to be carried to Mokpo port.

Watching Friday's operation from a ship following the transport vessel were relatives of some of the nine victims that remain missing.

Bringing the Sewol back to land would be a step toward finding closure to one of the country's deadliest disasters.

Once the ferry reaches Mokpo, government officials say it will take about a month for the ship to be cleaned and evaluated for safety.

Investigators will then enter the wreckage and begin a three-month search for the remains of nine missing victims and for clues further illuminating the cause of the sinking, which has been blamed on overloaded cargo, improper storage and other issues.

"That was how it (Sewol ferry) looked on 16 April, 2014. When the ferry capsized. What was I saying at the time? I asked (people and the government) to save them (the children on board). I asked them to save my child. Now, it is time for us to find our children. Rather than crying and being sad and depressed, we should be finding our children now. To find our children. So now, I am going to find my child with my own hands."

A 6,800-ton South Korean ferry was being brought to Mokpo port on Tuesday nearly three years after it capsized and sank in violent seas off the country's southwestern coast.

The ferry was hoisted to the surface last week, an emotional moment for South Korea as it searches for closure to one of its deadliest disasters.

More than 300 people - most of whom were students on a high school trip - died when the Sewol sank on 16 April 2014, touching off an outpouring of national grief and soul searching about long-ignored public safety and regulatory failures.
