Thank you for having followed our live coverage of the events in Istanbul.
Here is how things stand as we wrap up on Wednesday afternoon:
- Three gunmen attacked Istanbul's Ataturk airport, the biggest in Turkey, on Tuesday evening and detonated explosives when police shot at them
- The death toll has risen to 41, of whom most were Turkish nationals - 13 foreigners also died
- 239 people were injured and nearly half of them have already left hospital
- Investigators are examining CCTV footage and mobile phone videos to piece together what one official called a "jigsaw puzzle"
- Nobody has claimed the attack yet
- Turkey's prime minister says early indications are that the so-called Islamic State group is responsible - they've criticised the Turkish government for allying with the US-led coalition against them
- The US government, Pope Francis, the head of Nato and the Belgian prime minister were among those to condemn the attack
- Russia's President Putin offered condolences to Turkey's President Erdogan this morning, the first time they've spoken since Turkey shot a Russian military jet in November
