• At 2 pm on Monday, the Danish Maritime Authority alerts that a gas leak has occurred in a Nord Stream 2 pipeline in the waters off Bornholm.

At 20:00 it is confirmed that Nord Stream 1 is also leaking.

The Swedish Maritime Administration receives warnings at about the same time.

Ships were prohibited from operating near the sites.

• On Tuesday, SVT reveals that several Swedish and Danish measuring stations registered strong underwater explosions in the same area during Monday.

The first explosion was recorded at 2:03 a.m. on Monday night and the second at 7:04 p.m. on Monday evening.

• The leaks are in Sweden's and Denmark's economic zones, which is not the same as the suspected sabotage taking place in territorial waters.

There is also no Swedish or Danish ownership in the gas pipelines.

Therefore, it is not an attack that took place on Swedish or Danish territory, said Prime Minister Magdalena Andersson (S) on Tuesday evening.

• At 20:00 on Tuesday evening, first the Prime Minister of Denmark and then the Prime Minister of Sweden confirm that it is probably sabotage.

Several authorities and assessors in many countries note the same.

• Nord Stream 2 is estimated to contain 300 million cubic meters of stagnant gas.

The Danish Energy Agency stated on Wednesday afternoon that half of all gas is gone from the pipes.

- On Sunday, everything is gone, said the head of the Swedish Energy Agency, Kristoffer Böttzauw, at a press conference in Copenhagen.

• During Wednesday, it is confirmed that Säpo will take over the investigation.

"The security police are taking over the investigation because it may be a serious crime that may at least partially be directed against Swedish interests.

It is also not possible to rule out that a foreign power is behind it," writes Säpo in a press release.

• During Wednesday evening, Prime Minister Magdalena Andersson (S), Foreign Minister Ann Linde (S) and Johan Norrman, head of the Coast Guard's operational department, held a press conference.

During it, it emerged that the Swedish government has been in contact with a number of European countries.

Many have offered their help if needed, said Foreign Minister Ann Linde (S).
