Leaders of the G8 industrialised nations have been meeting in the central Italian town of L'Aquila, badly hit by an earthquake in April.
The venue, which was switched from a former US base in Sardinia, has presented logistical challenges for the Italian authorities.
Safety has been a concern in the town's damaged buildings, and contingency plans are in place in case of further tremors.
The leaders were given tours of the earthquake zone and met those involved in rescue efforts.
Leaders of the G5, a group of the biggest developing nations, have been meeting on the sidelines.
Protests against the summit have continued, but at a safe distance from the venue.
What are these?
