The death toll from the massive earthquake that shook eastern Turkey over the weekend rose to 535 Thursday, up from 471 the day before, but crews have been able to rescue 185 people alive from the rubble, Turkish officials said.

In addition, about 2,300 people were injured by the 7.2-magnitude earthquake that struck Sunday, according to the Turkish Disaster and Emergency Relief Agency.

Meanwhile, crews rescued 18-year-old Imdat Padak alive from the rubble of an apartment building in Ercis almost 100 hours after the earthquake, the semi-official Anatolian new agency reported.

After teams from Azerbaijan retrieved him, Padak was taken to a hospital for initial treatment, and then was airlifted by helicopter to Van.

Padak appeared not to have any significant trauma, but was suffering dehydration. He is reported to be a student from the village of Kiziloren and was taking courses while preparing for university entrance exams.

Earlier in the week, crews pulled a 2-week-old baby, Azra Karaduman, alive from the debris.

The developments came as there were reports of a moderate earthquake in the country's south.

A 5.2 earthquake hit about 200 kilometers (125 miles) south of the center of Sunday's quake, near the border with Iraq, the U.S. Geological Survey reported.

There were no immediate reports of damage from the latest quake.

Padak was the latest of several people found alive in the rubble days after Sunday's quake. On Wednesday rescuers pulled two people from collapsed buildings.

Britain has pledged emergency tents for more than 5,500 people whose homes were destroyed, Home Secretary Theresa May said during a visit to Turkey Thursday.
