No missing children at collapsed Mexico school following earthquake

All the pupils at a school in Mexico City that collapsed after this week's 7.1 magnitude earthquake have been accounted for, the country's navy has said.

Earlier reports suggested that a 12-year-old girl was trapped in the rubble and had been able to communicate with rescuers.

But in an update, Navy Assistant Secretary Angel Enrique Sarmiento said that while there were traces of blood and other signs suggesting someone might still be alive, it was probably a school worker.

Mr Sarmiento said 19 children and 6 adults died in the school collapse, and that 11 children were rescued.

"We have done an accounting with school officials and we are certain that all the children either died, unfortunately, are in hospitals or are safe at their homes," he said.

:: Why are there so many earthquakes in Mexico?

The official death toll of Tuesday's 7.1-magnitude earthquake has now risen to 273, with Mexico City bearing the brunt of the deaths and damage.

The capital's mayor, Miguel Angel Mancera, said the number of people confirmed dead in the city had risen from 100 to 115. More than 40 buildings have collapsed.

Rescuers are continuing to search for survivors using thermal scanners and cameras to locate bodies, and ropes, pry bars and sledge-hammers to break up and move rubble.

:: Who are the hero 'moles' of Mexico City?

Emergency services have been joined by Mexico's "mole" rescue workers, who formed as a volunteer search and rescue group in the aftermath of the devastating quake that struck Mexico City in 1985.

They have worked at disaster sites across the world including the 2001 attacks on the World Trade Center in New York.

Oscar Guevara, a doctor from the central Mexican state of Queretero who joined the Topos of Tlatelolco search and rescue group in 2010, said they had found three people alive, along with some bodies, in the rubble of one building.

President Enrique Pena Nieto has declared three days of national mourning, but said the race to pull out survivors was still the priority.

"Every minute counts to save lives," he tweeted.

Mexican actress Salma Hayek has donated $100,000 (£74,000) to help victims of the quake, posting an emotional video on Instagram, imploring others to help if they can.

She explains that she "lived through the aftermath" of the 1985 Mexican earthquake which killed 5,000 and caused serious damage to Mexico City.

Harry Potter author JK Rowling has also tweeted, calling the disaster "heartbreaking" and appealing for others to donate.

The quake was centred near Raboso in Puebla state, 76 miles (123km) southeast of Mexico City, but the shaking in the capital was almost as intense.

When it struck, panicked workers fled from office buildings and clouds of dust rose up from the crumbling facades of damaged buildings.

The earthquake came less than two weeks after an 8.1 magnitude tremor in southern Mexico killed at least 98 people.

Amid the latest quake, the Popocatepetl volcano near the capital had a small eruption, flattening a church on its southern slopes and killing 15 people attending a mass.
