Lula calls for South American unity at summit in Brazil

Brazilian President Luiz Inacio Lula da Silva called for South American unity as he welcomed fellow leaders for a "retreat" to strengthen ties in a region where left-wing governments are newly back in style.

Eleven of the continent's 12 heads of state attended the summit in Brasilia, the first of its kind in nearly a decade, which Lula said turned the page on an era of divisions. The meeting also included fellow recently elected leftists Gabriel Boric of Chile and Gustavo Petro of Colombia.
