ATHENS: A last-gasp goal by Giorgos Tzavelas allowed Greece to escape with a 1-1 draw against Bosnia and Herzegovina in a World Cup qualifier on Sunday, while Group H leader Belgium crushed Estonia 8-1.

Belgium remains perfect with 12 points from four games, and has scored 21 goals with only one conceded.

Dries Mertens scored in each half against Estonia, while Romelu Lukaku snatched two late goals to add to the visitors' misery.

Second-placed Greece trails Belgium by two points after being held at home, while Bosnia and Herzegovina is a further 3 points behind.

Tzavelas scored with a blistering shot outside the area in the fifth minute of injury time after Bosnia's defense only half-cleared a long throw-in by Sokratis Papastathopoulos.

Bosnia, which dominated most of the game in Piraeus, took the lead in the 33rd minute after Miralem Pjanic's free-kick bounced off the right post and then goalkeeper Orestis Karnezis' back before finding the net.

The game was stopped for five minutes after the goal, with some Bosnian fans lighting and throwing flares — and broken seats — while some Greek fans chanted anti-Bosnian slogans.

Tension had built ahead of the game when a group of Greek fans attacked and slightly injured a Bosnian, who claimed his attackers were shouting "Kosovo is Serbia."

On the field, Costas Fortounis nearly equalized in the 54th, but goalkeeper Asmir Begovic deflected his shot into the right post.

Both teams ended the game with 10 men, with Kyriakos Papadopoulos getting a red card for striking Edin Dzeko - in his attempts to wrestle the ball away - while Dzeko got a second yellow card for pulling Papadopoulos' shorts down in the same 80th-minute incident.

In Brussels, Estonia found itself 3-0 down in the first 25 minutes through goals by Thomas Meunier, Mertens and Eden Hazard. And although the Estonians pulled one back in the 29th, through Henri Anier, it was all downhill from there.

Yannick Carrasco made it 4-1 in the 62nd, Ragnar Klavan gifted the Belgians with an own goal two minutes later and Mertens scored his second four minutes after that. Lukaku added two more in the 83rd and 88th.
