POZZALLO, Sicily — About 400 migrants aboard two border patrol ships disembarked in a Sicilian port Monday after a half-dozen European countries promised to take some of them in rather than leave Italy alone to process their asylum claims.

Italy’s antimigrant government had kept the two military ships from docking at ­Pozzallo for two days until other countries stepped up in the latest standoff forced by Italy over migrant rescues.

Early Monday, the ships came into port and disembarked their passengers, who were seen being screened at dawn. Doctors at the scene said one of the men was hospitalized in critical condition with pneumonia, while the others were in generally good health but suffering from scabies.

On Sunday, Germany, Spain, and Portugal each agreed to accept 50 of the migrants, following similar offers by France and Malta. They were responding to a request by the Italian premier, who sent individual letters to each EU member asking for a firm gesture of solidarity so that ­Italy isn’t left alone to cope.

But not everyone agreed. The Czech Republic rebuffed the appeal and called the distribution plan a ‘‘road to hell’’ that would just encourage more human traffickers.
