European
Commission President Jean-Claude Juncker is due to announce plans to
tackle Europe's worst migrant crisis since World War Two.
Under the proposals, 120,000 asylum seekers will be distributed among EU member countries, with binding quotas.
This comes after thousands of mainly Syrian migrants began trekking northwards through Europe this weekend.
Hungary has been warned to expect an additional 40,000 migrants by the end of next week.
Vincent
Cochetel, a regional co-ordinator for the UN refugee agency UNHCR, also
urged the Hungarian authorities to improve registration and reception
procedures.
Hungary has become a key point on the journey north for the migrants, with more than 150,000 people arriving this year.
The
authorities there are now reinforcing a border fence designed to keep
migrants from entering from Serbia and are toughening asylum laws.
In a separate development Australia, which has been under pressure to do more to help displaced people,
has announced plans to take in more Syrian refugees.
The government said it would accept 12,000 Syrian refugees from persecuted minorities.
'Important first step'
The migrant crisis and how to resolve it has exposed divisions within the EU.
The Czech Republic, Slovakia, Poland and Romania have opposed the idea of mandatory quotas.
On
Tuesday, though, Poland appeared to soften its position. Prime Minister
Ewa Kopacz said the country would accept more migrants than the 2,000
it first offered to take.
Germany has welcomed Syrian migrants,
waiving EU rules and saying it expects to deal with 800,000 asylum
seekers this year alone. Vice Chancellor Sigmar Gabriel said his country
could cope with 500,000 a year for several years to come.
The planned EU quota system would allocate 60% of
migrants now in Italy, Greece and Hungary to Germany, France and Spain,
reports say.
The numbers distributed to each country would depend
on GDP, population, unemployment rate and asylum applications already
processed.
Countries refusing to take in migrants could face financial penalties.
Also planned are measures to help the economies of countries in the Middle East and Africa, and deter people-smugglers.
German Chancellor Angela Merkel said on Tuesday that quotas were an "important first step".
Speaking
alongside the visiting Swedish Prime Minister, Stefan Lofven, she added
that the EU needed an open-ended "system to share out those with a
right to asylum".
'Dysfunctional' approach
The UN High Commissioner for Refugees, Antonio
Guterres, has meanwhile labelled the EU's approach to asylum seekers
"dysfunctional".
"It is clear that this is a serious crisis, but
for me it is also clear that if Europe would be properly organised, it
would be a manageable crisis. We are talking about 4-5,000 people per
day, in a union that has 508 million people".
The
mass migration has seen those seeking an end to persecution, conflict
and hardship travel by boat, bus, train and on foot, from Turkey, across
the sea to Greece, through Macedonia and Serbia, and then to Hungary
from where they aim to reach Austria, Germany and Sweden.
Hundreds
continued to cross on Tuesday from Serbia into Hungary, where there
were scuffles with police and a protest against being registered, with
migrants chanting "no fingerprints".
A Hungarian TV camerawoman was sacked after she was accused of deliberately tripping up a male migrant carrying a child.
The
two migrants, who fell to the ground, were among dozens fleeing police
during a disturbance near a registration centre at Roszke.
More migrants came northwards through Macedonia from the border with Greece.
The UNHCR says a record 7,000 Syrian migrants arrived in Macedonia alone on Monday and 30,000 were on Greek islands.
The
Greek island of Lesbos has seen a build-up of 20,000 migrants, some
living in squalid conditions while they wait to be processed.
The UNHCR meanwhile highlighted the growing scale of the challenge,
releasing new figures that suggest it expects 400,000 migrants to have arrived in Europe by sea in 2015.
The
majority are Syrian, and the UN says many are now seeking a better life
in Europe because of poor conditions in refugee camps in Jordan and
Lebanon - caused in part because of a drastic shortfall in multilateral
aid programmes.
A note on terminology:
The BBC uses the term migrant to refer to all people on the move who
have yet to complete the legal process of claiming asylum. This group
includes people fleeing war-torn countries such as Syria, who are likely
to be granted refugee status, as well as people who are seeking jobs
and better lives, who governments are likely to rule are economic
migrants.
