7,000 migrants in race to beat freeze.
ALMOST 50,000 migrants and refugees are pouring into Europe every week as winter approaches.
About 7,000 people a day landed on Greek islands last week- up from 4,500 in September, the International Organization for Migration revealed.
With autumnal weather taking hold and temperatures dropping, more desperate Syrian and Afghan families are making the perilous sea crossing from Turkey before conditions worsen.
One such journey ended in disaster last night as a boat carrying Syrians to the island of Samos sank in atrocious conditions. Witnesses claimed children were heard screaming.
Human rights monitor Peter Bouckaert tweeted: "There has been no further contact with the boat sinking off Samos.
"Horrible to even imagine what is happening." He said coastguards were searching but the wind was so fierce it had shredded flags on nearby Lesbos.
Half a million migrants have travelled to Europe this year and 3,000 have died en route.
Police in Spain have arrested four suspected human traffickers from Pakistan and China.
