Nigeria reach semifinals after pitch invasion 
LAGOS, Feb 7 (Reuters) - Jubilant Nigerian fans invaded the 
pitch and caused play to be delayed for 10 minutes as their team 
came from behind to beat Senegal 2-1 in extra time and reach the 
African Nations Cup semifinals on Monday. 
Nervous Senegalese players refused to return to the field 
after being engulfed by a mob of fans, who rushed on to the 
field after 18-year-old subsitute Julius Aghahowa gave Nigeria a 
2-1 lead in the second minute of extra time. 
The golden goal rule is not used in the competition. 
Police seemed slow to react and Senegal at one stage 
appeared to walk towards their dressing room before finally 
agreeing to return to the field. 
Aghahowa had also scored Nigeria's equaliser six minutes 
from time after a superb goal by Senegal's Kalidou Fadiga early 
on had threatened a major upset. 
Nigeria's Austin Okocha was sent off for clashing with a 
defender in extra time.
