Chinese censors on Thursday cut off CNN's coverage of the deaths of 39 Chinese nationals found in a truck in England the day before.

It is not uncommon for China to censor negative or sensitive stories covered by international broadcasters.

Belgium has now opened an investigation into the deaths of 39 people on a truck in the UK, according to the country's Federal Public Prosecutor’s Office.

In a statement released Thursday morning it said the investigation “will focus on the organizers of and all other parties involved in this transport.”

The preliminary findings of the prosecutor outline the origins and initial movements of the container carrying the group. Here's their timeline of the container's movements:

It arrived at Zeebrugge port in Belgium on Tuesday at 2:49 p.m. CET (1:49 p.m. BST)

It left the port that same afternoon

It arrived in Purfleet in England on Wednesday at 1:00 a.m. CET (12:00 a.m. BST.)

It remains unclear when and where the victims entered the container.
