• More than 40,000 migrants set sail for Italy in unseaworthy boats last year

• Italian government has called their migrant crisis 'increasingly glaring'

More than 4,000 migrants have arrived on Europe's shores by boat in the past two days, with the Italian government calling the crisis ‘increasingly glaring’.

The emergency comes days after Italy's Home Secretary Angelino Alfano warned that more than half a million migrants were ready to set sail from Northern Africa for Europe.

Italy's southernmost island, Lampedusa, is the gateway for illegal immigrants to enter Europe.

More than 40,000 people made the journey to Italy last year, often on unseaworthy boats.

So far this year 15,000 migrants have landed on the Italian coastline, a ten-fold increase on the first three months of 2013.

British experts believe one in five of them continue on to the UK.

Mr Alfano told Italian radio: ‘The landings are non-stop and the emergency is increasingly glaring.

'Right now two merchant ships are rescuing two boats with 300 and 361 people aboard.

'It appears there's at least one corpse on board’.

He added: ‘ Europe must take the situation in hand.’

The traffickers, who reap vast profits from the boatloads, are equipped with satellite phones and send out requests for help just 30 to 40 miles after leaving the Libyan coasts, he said.

One Italian Navy ship, the San Giorgio, was called to the rescue of four overcrowded boats containing 1,000 people, including women and children, who did not have life jackets.

 

The other 3,000 migrants were rescued by a combination of coastguard, patrol vessels and merchant ships before being brought ashore.

On Tuesday Mr Alfano called an emergency summit with police, Navy and coast guard officials participating in the rescue-and-surveillance operation to deal with the emergency.

Many boats have left North Africa and have been heading to the Italian island of Lampedusa - such as these migrants who arrived earlier this year in February

The arrival of migrants in February was partly due to a tragedy, where more than 80 migrants heading to the area were killed by a sinking boat - pictured are the migrants who survived arriving on board a coastguard vessel at the harbour of Lampedusa, Italy

Illegal migrants landing in the EU have to remain in the country where they first seek asylum.

But many hope to pass through Italy undetected to northern Europe, which has better job prospects and generous benefits.

In the wake of a tragic shipwreck last year in which more than 300 migrants died, Italy called for a pan-European search and rescue mission to intercept migrant boats 'from Cyprus to Spain'.
