RIO DE JANEIRO, March 14 (Xinhua) -- Inter Milan loanee Gabriel Barbosa and Colombian forward Fernando Uribe struck second-half goals as Flamengo beat LDU Quito 3-1 in their Copa Libertadores group match here on Wednesday.

Everton Ribeiro put the Brazilian side ahead in the ninth minute at the Maracana Stadium by sweeping in a low first-time effort after Diego's assist.

Gabriel Barbosa rifled in Flamengo's second goal shortly after the hour mark before Uribe netted from close range nine minutes from time.

Cristian Martinez pegged a goal back for the Ecuadorian outfit by converting a stoppage time penalty.

The result gave Flamengo a three-point lead over LDU Quito at the top of Group D, with Bolivia's CD San Jose and Uruguayan side Penarol having a game in hand.

In Buenos Aires, defending champions River Plate continued their lackluster start to the tournament with a goalless home draw against Chilean qualifiers Palestino.

River are second in Group A with two points from two matches, three points behind leaders Internacional of Brazil, who secured a 2-0 home win over Peru's Alianza Lima earlier on Wednesday.

In other matches, Paraguay's Cerro Porteno overcame Venezuelan side Zamora 2-1 at home, San Lorenzo of Argentina beat Colombia's Junior Barranquilla in Buenos Aires and Universidad Catolica of Chile secured a 2-1 home victory over Argentine club Rosario Central.
