A private jet has crashed in Florida, killing all nine people on board. Investigators believe parts of the aircraft may have broken off in the air. This was reported by Qazaqyia.kz citing BBC News.

The Learjet 60 was bound for the Bahamas from Austin, Texas, when it nosedived into a multi-lane highway and exploded on impact. The crash occurred on Sunday at around 12:50 local time on Military Trail, a six-lane road featuring businesses and restaurants in Palm Beach.

The US National Transportation Safety Board (NTSB) said weather conditions would be a major focus of the investigation, but that it was struggling to access the wreckage due to a huge crater on the road formed by the jet.

"The biggest obstacle that we're going to have is recovering the major wreckage from the impacted crater on the roadway," lead investigator Tim Monville said at a news conference on Monday.

The NTSB said the crater, near the entrance to a mobile home park, was partially filled with water because of severe storms. Heavy rainfall and thunderstorms had been reported in the area at the time of the crash.

Debris was scattered across sports fields, businesses and homes in the area.

"We do have some evidence that there was some breakup of the aircraft before impact," the NTSB's Tom Chapman said. "We may find parts of the aircraft some distance away from the actual impact site."

Officials are also trying to find out whether a cockpit voice recorder was on board at the time of the crash and if it can be recovered.

Flight analysis indicates that the jet was plummeting hundreds of feet per second before crashing. In air traffic control audio recordings, someone in the cockpit can be heard reporting "moderate turbulence" and that the crew was "managing the ice". They can then be heard saying the plane was "picking up precipitation" and "we need to climb". Moments later, the same voice said the plane was descending at a rate of 10,000ft (3,048m) per minute.

An emergency was declared and they can be heard yelling "we are in an overspeed condition descending 20,000ft per minute", before saying, "we are going to crash into the ground".

Seven passengers died on board the flight. They were named in a joint statement as tech entrepreneur Adam Robinson, his wife Helen Sharp, and their two children — Emma, four, and Charlie, two — as well as Rachael Reed, Charmi Fehr and Anita Maria Cetina.

The pilot was named in media reports as Jeffery Gregory, while Nathalia Filgueiras, 20, who earned her pilot's licence when she was 17, was reported to be the copilot.

One man in a car on the ground sustained a leg injury.

Robinson and Sharp's family described them as "devoted parents" and said their children were "the light of their lives". "Helen and Adam were the love affair that will last forever. Their warmth, generosity and gift for making people feel welcome touched so many lives," the statement reads.

On his LinkedIn page, Robinson described himself as the founder and CEO of RB2B and Retention.com, and the CEO of Moltsets. Helen Sharp was an artist, according to media reports. Robinson previously worked at global financial services business Lehman Brothers and the banking group Barclays. The BBC has contacted the companies for a statement.

The joint statement also named Anita Maria Cetina and said she "cared for Emma and Charlie with tenderness and devotion, and she was truly part of the family". It added: "She showed us a legacy of unconditional love and devotion."

Rachel Reed and Charmi Fehr were described in the joint family statement as "full of joy and adventure". "They loved their people fiercely, fully and without hesitation. From the moment they met, they were all in on each other and the life they were building."
