Rescue chief says 'no idea' when Korea ferry recovery over

SEOUL - The head of the operation to retrieve bodies from a sunken South Korean ferry admitted Friday he had "no idea" when it would be over, as furious relatives accused recovery teams of dragging their feet.

In a briefing to reporters on the southern island of Jindo - close to the disaster site - Navy Captain Kim Jin-Hwang spoke of divers finding rooms crammed with up to 48 bodies during their search missions over the past week.

The confirmed death toll stood at 183 on Friday, but 119 people remained unaccounted for - their bodies believed still trapped in the ferry that capsized on April 16 with 476 people on board.

Although all hope of finding survivors has been extinguished, there is still anger and deep frustration among relatives of the missing over the pace of the recovery operation off the southern island of Jindo.

Gentle tides and good weather have helped the dive teams in recent days, but the search conditions inside the ferry are still challenging and rescuers are only managing to retrieve around 30 bodies a day.

Making up the bulk of the passengers on the 6,825 tonne Sewol when it sank were 325 high school students - around 250 of whom are either confirmed or presumed dead.

Kim said his divers had found one dormitory room - that would normally have held around 31 people - packed with the bodies of 48 students wearing lifejackets.

He stressed that retrieving the bodies was far harder than finding them, with divers unable to spend much longer than 10 minutes inside the ship at a time.

Many of the corridors are blocked by plywood boards and other debris and only one-third of the rooms on board have been accessed so far, he said.

"It's very stressful," Kim said, adding that the divers were all too aware of the criticism from the families that they were not working hard enough.

On Thursday evening a group of irate parents stormed into the Jindo office of the deputy head of the South Korean coastguard and roughly manhandled him down to the island harbour.

He was kept there most of the night, sitting on the ground, along with the coastguard chief and Marine Minister Lee Ju-Young, while the relatives accused them of lying about the recovery operation and demanded they bring in more resources.

The bereaved families have said they want all the remaining bodies removed from the ferry before the weekend - a demand that Kim's comments made clear could not be met, especially with a bad weather front moving in.

"We know that weather conditions will worsen considerably and currents will become stronger from Saturday," a coastguard spokesman said.

Storm warnings could be issued on Saturday or Sunday for the area around the rescue site.

Rescuers have not found a single survivor since 174 people were pulled to safety on the day of the accident.

It took divers working in difficult and dangerous conditions more than two days to get into the sunken ferry and two more days to retrieve the first bodies.

Many relatives believe some of the victims may have survived for several days in trapped air pockets, but perished in the cold water after no rescue came.

As a result some have asked for autopsies to be performed, to see if it would be possible to determine the precise cause and time of death.

The Sewol's captain, Lee Joon-Seok, and 10 crew members have been arrested on charges ranging from criminal negligence to abandoning passengers.

The captain has been particularly criticised for delaying the evacuation order until the ferry was listing so sharply that escape was almost impossible.

Prosecutors have raided a host of businesses affiliated with the ferry operator, the Chonghaejin Marine Company, as part of an overall probe into corrupt management.

As part of their widening probe, prosecutors issued travel bans Friday on eight current and former executives of the Korea Register of Shipping - the body responsible for issuing marine safety certificate.
