Pope Leo XIV spends the Fourth of July on Lampedusa, prays at a migrant cemetery and celebrates Mass to honor tens of thousands who have died trying to reach Europe.He tells leaders in the US and Europe that immigration is a test of moral responsibility, criticizes past deportation programs in the Donald Trump administration and warns that new EU rules and Italy’s intensified deportations risk undermining asylum rights.Humanitarian organizations say more than 35,000 migrants have gone missing in the Mediterranean since 2014, report deaths at sea are rising even as arrivals on the central route fall this year, and call for restored search-and-rescue and expanded legal pathways.
