Following sporadic outbreaks of unrest overnight, on Monday the migrants, with calm resignation, opted to be relocated in France while their asylum is considered.

Jean-Marc Puissesseau, chief executive of Calais port where migrants in January briefly occupied a ferry, told BBC radio he was "a very, very happy man". They may come after them. They will be offered placements in refugee centres across France.
Fears that migrants would refuse to leave, or simply return, in at attempt to reach Britain were heightened following weekend clashes with police officers. "There are more than 2,000 policemen there".
French officials on Monday told Reuters that the negotiations about unaccompanied child refugees were still ongoing, with officials from both sides of the channel still deciding on who will take the children with no familial ties in Britain.
Ms Bermann said 600 children are now in special centres in Calais waiting to be processed.
Britain has taken in almost 200 child refugees from the Jungle in the past week and is expected to take dozens more.
Many don't know where they will be sent.
Mrs Rudd said: "It is essential that we maintain as far as possible the anonymity of the young people coming over here and one of those reasons which was pointed out to me is that some of these young people, particularly the young women, are claimed by smugglers, by traffickers, to owe them money".
The dire security and humanitarian situation in the Jungle - situated on a former rubbish dump where migrants and refugees first established a camp in the early 2000s - has always been a bone of contention between France and Britain.
People in the queues said they had no idea where they were going but most seemed resigned to leaving.
Leonard Doyle, a spokesman for the International Organization for Migration, told Foreign Policy in a phone call on Monday that this effort is "certainly more determined", but warned against seeing this round of clearing out as the end of the Calais camp.
While small scuffles broke out and punches were thrown, most people waited patiently, crammed inside the barriers, which armed riot police then widened to give them more space.
Closely watched by more than 1,200 police, the first of hundreds of buses began transferring migrants to reception centers around France where they can apply for asylum.
The migrants were split into four groups: unaccompanied children, adults, families and vulnerable individuals.
Buses carrying migrants have started moving from the camp to areas around France, Soraya notes. Officials are pleased with the evacuation process as there have been no problems so far.
For the moment, children are being moved to converted shipping containers at a site on the edge of the camp.
"We initially prioritised the transfer of children with family links to the United Kingdom, under the Dublin Regulation, and have now started the process of taking in those children without close family links", said a spokesman for the Home Office interior ministry.
There are about 900 unaccompanied minors in the camp.
