Rescuers have pulled a small dog alive from the rubble of a building that collapsed in Mexico after the country's deadliest quake in 32 years last week.
Helmeted members of a Japanese search and rescue team cradled the white dog and petted its head as they brought it down from the wreckage.
The rescue took place at an apartment building in a southern neighbourhood of the capital.
The building is one of a dwindling number of collapse sites where crews still have hopes of finding people alive.
As another aftershock jolted south-western Mexico on Sunday (local time), the death toll from Tuesday's magnitude-7.1 earthquake climbed to 320 people.
With thousands of buildings damaged, survivors slept on the street outside their homes and estimates of the cost of the earthquake ran as high as $8 billion.
Many have been traumatised by the second major quake to strike Mexico City in their lifetime after a devastating 1985 tremor killed an estimated 10,000 people.
Mexico's National Seismological Service director Xyoli Perez Campos warned more quakes were likely.
"We have already recorded more than 4,300 aftershocks," Mr Campos said.
"So more aftershocks are to come. What we don't know is if they are going to be of significant magnitude."
President Enrique Pena Nieto visited 12 communities in Mexico state, which borders the capital city, promising that aid would be directed only to those truly affected by the quake and the Government would help rebuild homes and businesses.
"I am publicly promising that … the affected homes, the families affected and the people in the whole of Joquicingo and the state of Mexico, get back on their feet," he said.
