The European Commission has warned EU countries that a broad cap on gas prices could be complex to launch and pose risks to energy security, amid calls from countries for Brussels to step in to tame high fuel prices, Reuters reported. The Commission shared a document with countries on Wednesday, analysing various options the EU could consider to curb high gas prices, after 15 of the bloc's 27 member states this week urged the EU to propose a cap on gas prices.

Although investigations into the simultaneous leaks in Nord Stream pipelines are in their early stages, European leaders, NATO and E.U. officials on Wednesday are firmly pointing to sabotage as the cause for the blasts, the Washington Post reported. Danish and Swedish authorities detected underwater explosions Monday and reported three breaches on the Nord Stream 1 and 2 gas pipelines, pouring tons of methane into the Baltic Sea. Seismologists in Denmark and Sweden said the two blasts they detected did not appear to be earthquakes, landslides or other natural activity.
