Diana Nyad out of the water, fourth attempt to swim from Cuba to Florida over

(CBS News) CBS News confirms 62-year-old Diana Nyad has ended her bid to swim across the Straits of Florida from Cuba. She had been pulled from the water on the fourth day of her attempt after more than 60 hours of swimming.

In a blog post on Nyad's website, Candace Hogan wrote Nyad shook her head in anger as she was pulled aboard her escort boat and talked of going back into the water.

Hogan wrote, "Fully alert and articulate, (Nyad) asked, 'When can I get back in? I want full transparency that I was out. But I have plenty left in me and I want to go on.'"

But it was decided that she would not go on for the safety of herself and the team accompanying her.

Mark Sollinger, operations director with Nyad's team, told CBS News he made the decision to pull Nyad from the water this morning at 12:55 a.m. "We had a very, very large squall ... move into our location very, very rapidly so that combination of things made it very, very, very dangerous, not only for Diana but any other member of our team in the water."

"This morning as a team we decided that to continue ... just wasn't going to make sense on a lot of levels, including the overall safety, not only of Diana but the overall team."

Sollinger told CBS News Nyad's lips are very swollen, as well as one of her eyes. He added, "(She has) exhaustion, you know, what you would expect from someone attempting to do probably what almost maybe one or maybe two other people on the entire planet would ever attempt doing."

Nyad had been expected to arrive somewhere in the Florida Keys early Tuesday. She had hoped to celebrate her birthday Wednesday as the first person to complete that swim without a shark cage.

"CBS This Morning" spoke to members of Nyad's support team, and they said overnight Nyad suffered nine serious jellyfish stings. The support team, concerned about her health, worked to assess her health at that time.

The support team also told CBS News' Elaine Quijano that Nyad made very clear she did not want to get out of the water. In fact, one person, a team member, said "she's a tough, old bird."

Sollinger said Nyad's being comforted by her friends, and her vitals are being monitored by a medical team.
