More than a thousand migrants arrived in Italy within a few hours while hundreds of others, rescued by humanitarian vessels, were waiting for a port to receive them, NGOs and authorities said Sunday.

Between January 1 and July 22, 34,000 people arrived in Italy by sea compared with 25,500 during the same period in 2021 and 10,900 in 2020, Italy's interior ministry said.

More than 600 people attempting to cross the Mediterranean on board a drifting fishing vessel were rescued on Saturday by a merchant vessel and coastguards off Calabria, at the southern tip of Italy.

They were landed in several ports in Sicily.

The authorities also recovered five bodies of migrants who had died in so far undetermined circumstances.

On the island of Lampedusa, some 522 people from Afghanistan, Pakistan, Sudan, Ethiopia and Somalia, among others, arrived from the late hours of Saturday in 15 different boats from Tunisia and Libya.

According to the Italian media, the island's reception centre has been overwhelmed.

With a capacity of 250-300 people, it currently hosts 1,200, according to the Ansa news agency.

Offshore NGOs continued to recover hundreds of migrants in distress in the Mediterranean.

SeaWatch reported that it had carried out four rescue operations on Saturday.

"On board SeaWatch3, we have 428 people, including women and children, a woman nine months pregnant and a patient with severe burns," it said on its Twitter account.

OceanViking, operated by non-governmental organisation SOS Mediterranean, reported that it had recovered 87 people, including 57 unaccompanied minors, who were crammed onto "an overcrowded inflatable boat in distress in international waters off Libya".

The Central Mediterranean migration route is the most dangerous in the world.

The International Organization for Migration estimates that 990 people have died and disappeared since the beginning of the year.
