London: Laurent Koscielny earned Arsenal a deserved point at the Etihad Stadium with a late equaliser as Manchester City's stuttering start to the season continued.
The Gunners had much the better of the first half but could not make their dominance count and Joleon Lescott headed the hosts in front from a 40th-minute corner.
That looked like being the way it would stay as Arsenal struggled to find a way to goal, but Koscielny proved the unlikely hero with an unstoppable shot eight minutes from time.
Both sides wore black armbands to remember Greater Manchester Police officers Fiona Bone and Nicola Hughes, who were killed on Tuesday, and all sides of the ground stood for a period of applause before kick-off.
City's defence of their Premier League title had consisted of two scrappy wins and two draws, while they suffered a last-gasp defeat by Real Madrid in the Champions League on Tuesday.
They were at least boosted by the return of Sergio Aguero for the first time since the opening weekend of the season after a knee injury, and he had the first real chance of the game in the 14th minute with a curling shot that was pushed away by Vito Mannone.
The Gunners were taking on their opponents with real pace and in the 24th minute Carl Jenkinson did well down the right and pulled the ball back to Lukas Podolski, who skied his shot well over the bar.
In other matches, Tottenham scored two goals in a three-minute span in the second half to earn a come-from-behind 2-1 win over Queens Park Rangers to give manager Andre Villas-Boas his first home victory at the club.
Bobby Zamora had given the visitors the lead in the 33rd minute, but Tottenham equalised through an own goal by Alejandro Faurlin in the 59th.
In-form striker Jermain Defoe then secured the win for the hosts in the 62nd, tapping in a rebound from close range.
At Newcastle, the host club kept a clean sheet for the first time in this season with a 1-0 victory over Norwich at St James' Park.
