Demolition teams are due to return to the French port of Calais to dismantle more makeshift
shelters in the migrant camp known as the "Jungle".Overnight, riot police fired tear gas at
migrants who were hurling stones at the demolition squads.Authorities say the migrants must
move to shipping containers on another part of the site.But many fear this will require them
to claim asylum in France, and give up their hopes of travelling to Britain.The BBC's Anna
Holligan in Calais says that migrants, under cover of darkness, tried to access lorries on the
motorway heading towards the port.Riot police fired tear gas, forcing them back, she said.
Those living in the camp, mainly from the Middle East, Afghanistan and Africa, hope to cross
the Channel to the UK, often using people traffickers to try to enter illegally. French
authorities believe about 1,000 migrants will be affected by the eviction plan while aid agencies
say the number of people living there is much higher.About 100 shacks were dismantled on Monday.
Riot police fired tear gas after migrants began throwing boulders inside the camp. At least 12
shelters were set ablaze.More trouble broke out later as groups of migrants fanned out across
scrubland towards the motorway heading to the port.French media say about 150 people, some wielding
sticks and iron bars, walked on to the road to block vehicles.Riot police pushed them back into
the camp. At least four people, including activists from the UK-based No Borders group, were
arrested during Monday's unrest, police say.Earlier, Good Chance, a theatre group which works in
the camp, said police were stopping volunteers from entering the camp.French officials say public
areas in the camp such as places of worship or schools will not be affected and describe the
clearance as a "humanitarian operation".Conditions in the southern sector are squalid and the
camp's sprawling presence has become a controversial issue in both France and the UK.
Officials say migrants can either move into converted containers in the northern sector of the
camp, where there is room for 1,500 people, move to similar accommodation centres elsewhere in
France or claim asylum in France.But many residents are reluctant to leave the Calais area.
Afghan migrant Hayat Sirat told AP news agency: "Going to Britain... is what people [here] want.
So destroying part of the jungle is not the solution."On Macedonia's border with Greece,
there is just one small crossing-point which thousands of migrants waiting to continue their
journey to western Europe can pass through legally.They line up patiently, waiting their turn,
until eventually the Macedonian police officer decides to open the stark metal gate.
He checks their papers: they must be Syrian, Iraqi or Afghan and must have the right stamp on
their documents from the Greek authorities, otherwise he will not let them enter Macedonia.
But then after letting some through, the policeman abruptly shuts the gate again.His Greek
counterpart is furious.She had expected many more to be allowed through, and they had been queuing
up in the rain when they could have been keeping warm and dry in their tents.The increasing
restrictions on this border are sparking fears amongst the refugees and migrants, and aid workers,
that the border might eventually be completely closed off."The authorities and all the humanitarian
organisations that are operating here should have a contingency plan and that is what we are working
on at the moment," says Alexandros Voulgaris from the United Nations refugee agency, UNHCR.
"For instance UNHCR has been erecting some family tents so we have more available space in case it
is needed."Amongst those now ensuring this border is fully controlled are teams of foreign police
officers from Slovenia, Hungary, Croatia, Slovakia, the Czech Republic and Serbia.More European
Union member states are expected to join the mission soon, working alongside their Macedonian
counterparts patrolling the border and providing surveillance equipment, as well as helping to
register the migrants.
