Damage to submarine cables in the Red Sea is disrupting telecommunications networks and forcing providers to reroute as much as a quarter of traffic between Asia, Europe and the Middle East, including internet traffic, Paralel.Az reports quoting CNN.

Cables belonging to four major telecoms networks have been “cut” causing “significant” disruption to communications networks in the Middle East, according to Hong Kong telecoms company HGC Global Communications.

HGC estimates that 25% of traffic between Asia and Europe as well the Middle East has been impacted, it said in a statement Monday.

The company said it is rerouting traffic to minimize disruption for customers and also “extending assistance to affected businesses.”

HGC did not say how the cables had been damaged or who was responsible.
