RIO DE JANEIRO, Mar. 1 (Xinhua) -- Argentina's River Plate twice came from behind to earn a 2-2 draw with Brazilian side Flamengo in their opening Copa Libertadores group match here on Wednesday.

Henrique Dourado gave the hosts the lead by converting a 54th-minute penalty after Leonardo Ponzio brought down former Atletico Madrid midfielder Diego.

Rodrigo Mora equalized with a header after a Nicolas de la Cruz set piece before Everton restored the hosts' lead by latching onto a Lucas Patequa's through ball and firing a low shot past goalkeeper Franco Armani.

However River Plate continued to attack relentlessly and they got their reward when Camilo Mayada struck with a long-range effort three minutes from time to secure a valuable point away from home.

In Colombia, Brazil's Corinthians held Millonarios to a goalless draw at the Campin in Bogotá while in other matches Bolivian side Bolivar drew 1-1 with Delfin in Ecuador and Argentina's Estudiantes held Nacional to a goalless draw in Uruguay.
