MILAN, Italy – AC Milan goalkeeper Dida was hit by a flare thrown from the stands, and last night’s European Champions League quarterfinal against cross-town rival Internazionale was halted with about 15 minutes to play.

AC Milan was ahead 1-0 and set to advance on 3-0 aggregate when Dida was struck on his left shoulder by the flare in the 73rd minute. The game was stopped, and when referee Markus Merk tried to restart play 10 minutes later, more fireworks were thrown and Merk abandoned the match.

“Tonight’s episode doesn’t just hurt Inter, but the entire city of Milan,” AC Milan coach Carlo Ancelotti said.

Inter fans were upset that when Esteban Cambiasso put the ball in the net in the 71st minute, the goal was disallowed because of a foul. Last week end, scores of fans were arrested throughout Italy after confrontations with police and racist chants.

Andriy Shevchenko scored the only goal in the 30th minute. The Union of European Football Associations said it will decide whether the result of the game stands.

In yesterday’s other game, Chelsea lost 3-2 at Bayern Munich but advanced on 6-5 aggregate in the home-and-home, total-goals series. Frank Lampard, who scored two goals in the first leg, scored in the 30th minute and Didier Drogba added a tally in the 80th.

Today, Liverpool takes a 2-1 lead into its game at Juventus of Turin and Lyon travels to PSV Eindhoven following a 1-1 tie in last week’s first leg. Chelsea plays the Liverpool-Juventus winner.
