They say that 2016 is proving to be particularly deadly – with some 2,510 lives lost so far compared to 1,855 in the same period in 2015 and 57 in the first five months of 2014.
On a Mediterranean-wide basis, the odds of being among the dead are currently one in 81.
So far this year, 203,981 people have made the journey.
Almost three-quarters of these travelled from Turkey to Greece prior to the end of March.
Some 46,714 of these have travelled to Italy, almost the same as the total recorded there in the first five months of 2015 (47,463).
The North Africa-Italy route is dramatically more dangerous: 2,119 of the deaths reported to far this year have been among people making this journey, making for odds of dying as high as one in 23.
