A note received in several Belgian police stations indicates "imminent" terrorist attacks in France and Belgium, according to Belgian newspapers Wednesday.

Military vehicles are seen running through Brussels, capital of Belgium, on Nov. 21, 2015. The terror threat level in the Brussels region was increased to "maximum" on Saturday because authorities received information on the risk of an attack "similar to Paris," Belgian Prime Minister Charles Michel told a press conference.

This detailed note of information indicates that some jihadists would have left Syria 10 days ago to reach Europe via Turkey and Greece to carry out attacks in France and Belgium.

In Belgium, the shopping center City 2 in Brussels, a McDonald's restaurant and a police station are cited as possible targets.

"They would separate into two groups, one for Belgium and one for France, to commit attacks in different places," said the note, adding that these groups are already armed and would aim to commit an act classified as "imminent."

The implications of the note on safety measures however are not yet known.
