A gas interconnector with Romania being built since 2012 will not be operational before September, sources close to the construction say.
The 25-kilometer-long connection between Bulgaria's city of Ruse and Romanian Gyurgevo was initially scheduled to be ready in end-2013 at the latest, but the deadline was extended over technical difficulties.
Sources close to Bulgartransgaz, the system operator in charge of the interconnector, told website Econ.bg that a broken pipe going under the Danube river was the reason for the latest delay.
Attempts are now under way to pull the pipe out of the waters, with experts called on site to provide assistance, the informants have assured.
Apart from the link under construction, Bulgartransgaz intends to build another pipeline duplicating the first to boost capacities.
