Med migrants: 100,000 have made crossing, says UN

The number of migrants arriving in Europe across the Mediterranean has passed 100,000 since the start of 2015, according to the UN refugee agency.

The International Organisation for Migration says the figures represent a slight increase on 2014, and it expects a surge in the months ahead.

The majority of people are landing in Italy, but there has been a big increase in the numbers heading for Greece.
