Four undersea telecommunication cables were cut in the Red Sea, disrupting 25% of data traffic between Asia and Europe.

The cables are owned by private companies, with only about 1% owned by governments.

If all cables in the Red Sea were taken out, it would disrupt Europe's communication with India and East Asia, and North and East Africa.

Officials are still investigating the cause of the cuts, with theories including an anchor or deliberate disruption.

The Houthis have denied responsibility for cutting the cables, but some experts believe they could be capable of causing damage.

There are about 380 undersea cables in operation worldwide, with a total length of over 1.2 million km.
