• Elon Musk has posted tvideo and photos from inside the cave in Thailand where four boys and their soccer coach remain trapped. 
• Business Insider contacted SpaceX and they could not confirm or deny whether Musk was actually in Thailand.
• Musk has expressed his desire to help with rescue efforts on social media, and orchestrated the creation of a 'kid-size submarine.'
• Experts have previously said Musk's' plans may not be of much use due to huge numbers of rescuers already working on the mission and their success in so far bringing eight out of the 12 boys to safety.

Elon Musk has posted on photos and video from inside the cave in Thailand where four boys and their soccer coach remain trapped, but SpaceX won't confirm or deny his whereabouts. 

Musk posted photos on his Twitter account at around 5:00 a.m. local time Tuesday, reportedly from inside and outside of the cave. 

"Just returned from Cave 3," read the caption, likely referring to Chamber Three, a crucial part of the cave system about 0.3 miles (0.5 kilometers) from the entrance. "Mini-sub is ready if needed. It is made of rocket parts & named Wild Boar after kids' soccer team." 

In another post around 5:30 a.m., this time on Instagram, several people are seen wading through the waters of the cave with headlights guided by rope. 

"Just got back from Cave 3," the caption reads. 

Musk has been posting on social media about wanting to help rescue efforts in Thailand, but there has been no confirmation that he actually traveled to the Southeast Asian country himself.

Business Insider reached out to SpaceX to confirm whether Musk was actually in Thailand.

"We're not allowed to comment on his whereabouts," a SpaceX official said. 

Musk floated a plan on Twitter on Friday that could help rescue the boys and said engineers from his companies would travel to Thailand on Saturday. He suggested that a tube or series of tubes could be sent through the cave network and inflated to create a tunnel for the soccer team to travel through, without needing scuba gear.  

He has also suggested using a "kid-sized submarine," posting videos of the device on Sunday. 

But Musk tweeted Sunday morning that his team of SpaceX engineers didn't actually go to Thailand because rescue operations were already underway. 

Experts have previously weighed in on the Tesla, SpaceX, and The Boring Company CEO's proposed plans, and said Musks' team may not be of much use due to huge numbers of experts already working on the rescue. 

"It doesn't matter how much equipment you throw at it or how many dollars you throw at it, you may be reaching the limits of the technology in this particular situation," Anmar Mirza, National Cave Rescue Commission National Coordinator, told Slate on Saturday.

Rescue efforts over the last few days have managed to bring eight out of the 12 boys to safety, with divers going in and out of the caves to rescue them in groups of four. The rescued boys are currently in the hospital receiving treatment.

The remaining four boys and their 25-year-old coach remain in the cave, with highly-anticipated rescue efforts likely to resume on Tuesday morning.
