<p>"MOSCOW - An African-American exchange student has been stabbed by unknown assailants in a southern Russian city in an attack officials say may have been racially motivated.</p>
<p>Stanley Robinson, 18, of Providence, R.I., was in grave but stable condition Friday, said the head doctor of Volgograd’s Hospital No. 12. Investigators were trying to determine if the Dec. 5 assault on Robinson was a hate crime, said Svetlana Smolyaninova, a spokeswoman for the city police.</p>
<p>Robinson’s mother, who has spoken twice with her son by telephone since the attack, has no doubts…</p>
<p>Tina Robinson said her son had just finished working out at a gym and was headed for a bus stop when a single stranger approached and punched him. Robinson punched back, his mother said. The attacker then pulled a knife and stabbed Robinson in the chest and side, she said.</p>
<p>Relatives said Robinson, a graduate of East Providence High School in Rhode Island, was three months into a year’s stay in Russia. He was studying Russian on a program arranged by the American Field Service, or AFS."</p>
