Italian authorities cleared a migrant reception centre on the island of Lampedusa on Tuesday after a row over harsh living conditions that prompted detainees to sew their lips together in protest.

The facility, originally intended to house up to 850 migrants for up to 48 hours before transfer to other centres, has been steadily transformed into a long-term refugee camp where detainees are housed in overcrowded, unsanitary conditions, prompting domestic and international criticism.

Deputy Interior Minister Filippo Bubbico told the daily Avvenire newspaper that 200 migrants were being transferred to other centres.

Only 17 individuals, still caught up in registration pro­cesses that require their identities be established before they are moved, remain, he said.

Khalid Chaouki, a deputy of the centre-left Democratic Party who went to the island to demand action, announced on his Facebook page that transfers had started with two planes chartered to take migrants off the island.

“We should finally manage to free this centre up by today,” he wrote on Tuesday

Lampedusa, midway between Sicily and Tunisia, has been the centre of a chronic migration crisis which has worsened this year due to turbulence in the Middle East and Africa and the civil war in Syria.

The plight of the migrants left in Italy’s reception centres, starved of resources in the economic crisis, was highlighted last week by a video which showed people in another centre left standing naked in the cold while they were sprayed for scabies.

Last week nine North African immigrants stitched their lips together to protest against the conditions they were forced to live in and to demand their release. The United Nations High Commissioner for Refugees (UNHCR) last week described conditions in the Lampedusa reception centre as “unacceptable” and urged the Italian government to take urgent steps to remedy the situation.

Criticism of the centre has been a severe embarrassment to Italy, which has generally prided itself on the efforts its coast guard and navy have made to rescue thousands of migrants at risk of drowning in flimsy vessels.

At the request of the Interior Ministry, the Italian Red Cross sent eight staff to Lampedusa on Tuesday to boost its presence on the island following calls for it to take over management of the immigration centre.

The scandal at the migrant reception centre has fed into a wider debate over immigration in Italy and Prime Minister Enrico Letta said this week that his government would move to overhaul a law against clandestine immigration blamed by some for encouraging abuses against migrants. He said he also favoured moves to make it easier for the children of immigrants to gain Italian citizenship.
