ULAN-UDE /TASS/ Russia has called on Denmark to check whether there may be another explosive device at the Nord Stream gas pipeline, but has yet to receive an unambiguous response, Russian President Vladimir Putin said on Tuesday.
According to the Russian leader, a Gazprom vessel has spotted a column-or pillar-like object at a pipe joint some 30 kilometers from the terror attack site, which could potentially be an antenna for activating another bomb.
"But the Danish authorities responded to our inquiry by saying that they would have to think it over and will respond when they deem it appropriate. A rather vague response," he added.
