Madrid Social Center Becomes Focus for Clashes on Immigration, Welfare Reuters MADRID - A reception centerfor minorsin Madrid became the focus for clashing views on immigration and social welfare Thursday, aday afterpolice defused a grenade found there. The row around the center, in the suburb ofHortaleza, crystallizedworriesaboutimmigration and insecuritythathelped the far-right Vox party double its result in last month's election to become the third-biggest bloc in parliament. Vox repeatedly singled out the centerduring the campaign, with party leader Santiago Abascal denouncing "criminal foreign youngsters." Last month, an extreme right-wing group calledHogarSocial staged a protest at the gates, demanding the center's closure to restore "security." Police have made no arrests and some officials say gang violence may also have been behind the incident --with the device most likely thrown over the walls in a bag, according toTedax, the Spanish police bomb squad. The grenade contained a minimal explosive charge, and no one was hurt. Dangerous climate But government spokeswoman IsabelCelaasaid the inflammatory rhetoric from Vox, which staged a visit to the area by party spokeswoman Rocio Monasterio during the campaign, had created a dangerous climate. "Words are ultimately internalized and intoxicate our consciences," she told reporters. "We don't like thesewords. We believe they incite certain behaviors from citizens which are not desirable in a country which desires social cohesion and peace for all." With Spain's Socialist party still struggling to form a government after the election and separatist riots in Catalonia fresh in collective memory, Wednesday's incident has added to a volatile political climate in Spain. The center houses around 90 youngsters, most from North Africa, as well as some Spaniards. Several residents appeared wary, although according to city authorities,Hortalezahas some of the lowest crime rates in Madrid. "I don't feel safe passing by the center's gates alone," said Elizabeth Lopez-Vega, 34, who said a young man she was told lived in thecenterhad tried to steal her mobile phone last week. 'Nobody is teaching them' "They need more social educators," she said. "Nobody is integrating them intosocietyand nobody is teaching them a thing." Social workers say the center is run down, although it no longer suffers from the severe overcrowding it faced earlier this year, when minors were forced to sleep on the floor. But they feel "singled out, like a cross has been painted on our door," said one social workerwho asked to remain anonymous. "We're tired, afraidand fed up." .
