The CPI-M on Monday expressed "deep shock and outrage" over the suicide bombing in a park in Lahore in Pakistan that has killed more than 70 people, mostly women and children.
"This attack was particularly heinous as the perpetrators have themselves claimed that they targeted the Christian community who had gone to the park on Easter Sunday," the CPI-M said in a statement.
"The religious extremists who are resorting to such terrorist violence have to be put down firmly by the Pakistani authorities," the Communist Party of India-Marxist said.
The Sunday evening attack also left some 300 people injured.
