Taiwan’s coast guard detained a cargo ship and its Chinese crew on Tuesday and said it was investigating whether the vessel had deliberately cut an undersea telecoms cable in the latest possible breach of the island’s communication lines.

The Taiwanese coast guard has detained a Chinese cargo ship and its crew as it investigates the destruction of an undersea communication cable.

This is the latest in a series of incidents in recent years in which undersea Taiwanese cables have been damaged — with Taipei in some instances blaming China. Earlier this year, a Chinese cargo ship was suspected of severing a link northeast of the island.
