Regional leaders meet after undersea telecoms cables severed, while Chinese ship remains at anchor nearby

The Swedish prime minister, Ulf Kristersson, has said the Baltic sea is now a “high risk” zone as he met Nordic and Baltic leaders days after a suspected sabotage attack on undersea cables.

The Swedish prime minister declined to speculate on who may have been responsible for the severing of two fibre optic telecoms cables in the Baltic last week. A Chinese ship – the Yi Peng 3 – that sailed over the cables about the time they were severed has remained anchored in the Kattegat strait between Sweden and Denmark since 19 November.
