New York, Jumada II 15, 1437, March 24, 2016, SPA -- The UN children's fund (UNICEF) said Thursday that 86.7 million children under the age of seven have known no life outside of conflict, according to dpa. Growing up in a conflict zone, where they experience traumatic events and live under constant stress, children risk impairment to important brain development, leading to possible permanent emotional damage, UNICEF warned. Security, family, friends, play and routine - exactly the items crucial for children to develop learning skills - are largely lost in such difficult circumstances, UNICEF head for early childhood development Pia Britto said in a news release. --SPA 03:27 LOCAL TIME 00:27 GMT www.spa.gov.sa/w
