The bodies of 74 migrants who drowned in the Mediterranean trying to reach Europe have washed up on a beach west of the Libyan capital, the Red Crescent said Tuesday.

Residents of the village of Harcha, outside Zawiya, 45 kilometres (30 miles) from Tripoli, alerted the emergency services after finding a wrecked boat on the beach with bodies inside, the Red Crescent said.

More were discovered elsewhere on the beach and still more were feared to be in the sea.

A long row of black and white body bags was seen lined up near the water's edge.

"We don't have an appropriate vehicle to transport the bodies or a cemetery for unidentified bodies to bury them in," the group said.

"Some bodies are still on the beach and others that we can't reach are still floating in the water."

The International Organization for Migration (IOM) said the boat was reported to have foundered on Sunday, leaving as many as 100 people dead.

"Traffickers reportedly stole the engine and left it to drift," the agency said.

"A survivor, reportedly in a coma, was transferred to hospital."

The agency said that if confirmed, the deaths would bring the total number of migrants killed trying to cross the Mediterranean so far this year to more than 365.

It said that 187 migrants were rescued off Zawiya on Saturday, and were currently being held in a detention centre.

The tragedy is believed to be the worst since around 180 people were estimated to have died on January 14 when a migrant boat capsized off the coast of Libya.

Since then, hundreds of people have been plucked from the waters north of the African nation, including 700 on January 30 alone off the western city of Sabratha.

- 'What price #humanity?' -

On Tuesday Italy's coast guard said it rescued around another 630 migrants off the coast of Libya from two drifting vessels, a large boat and a rubber raft.

"74 bodies on a Libyan shore. Each testament to #indifference, a tragedy, entirely preventable. What price #humanity?" tweeted Elhadj As Sy, head of the International Federation of Red Cross and Red Crescent Societies (IFRC).

The IOM said migrant arrivals in Italy had risen sharply this year compared with the same period of 2016.

As of Sunday, 10,120 had arrived compared with 6,589 between January 1 and February 18 last year.

People smugglers have taken advantage of the chaos gripping Libya since the 2011 revolution to greatly boost their lucrative trade.

Most departures take place from the west of Libya, usually heading for Italy 300 kilometres (190 miles) away across the Mediterranean.

Europeans are considering measures aimed at blocking the arrival of thousands of migrants, alarming NGOs which fear that those stranded in Libya may suffer mistreatment.

In the absence of an army or a regular police force in Libya, several militias act as coastguards but are often accused themselves of complicity or even involvement in the people-smuggling business.

UN Libya envoy Martin Kobler visited a migrants' camp in Tripoli on Tuesday, and said he would be discussing their voluntary repatriation with the authorities.

"They do not have enough food. They have really a serious situation here and it's very important to solve their humanitarian problem," he said.

"If they want to return they must be given the chance to return."

According to the United Nations, more than 5,000 people died last year in attempts to cross the Mediterranean and reach Europe, most of them after embarking from the Libyan coast after paying people smugglers.

This was the highest annual toll on record.

Unlike previous years, winter has not brought an end to the migrant arrivals, just a reduction in the numbers.
