The International Federation of Red Cross and Red Crescent Societies (IFRC) says it will increase the aid it gives to Greece.
It comes after coastguards dealt with a huge rescue operation off the island of Lesbos. In terms of numbers, the biggest rescue of the crisis so far.
The International Organisation for Migration (IOM) estimates at least 435 people drowned in October alone, trying to reach Greece across the Aegean Sea.
The IFRC coordinates humanitarian groups around the world.
It hopes 200,000 migrants will benefit from the nine million euros extra funding, which will pay for aid and staff.
Greek Prime Minister Alexis Tsipras has accepted an invitation from his Turkish counterpart Ahmet Davutoğlu to visit Ankara. The migrant crisis is likely to feature prominently in talks.
The crisis in numbers
- 600,000 – the number arrived in Greece from Turkey this year
- 8,000 – the number arriving every day
- 435 – the number drowned in October
- 1,400 – the cost in euros of a one-way trip from Turkey to Greece with smugglers
- 25 – the cost in euros of the same two-way day trip for tourists
- 9 million – the extra funding in euros from the IFRC

Necessary – but is it sufficient?

Some say system has got off to a good start.
Some say more staff are needed.
While others think the crisis is a question of policy failure.
