Afghan rescuers scrambled Monday to pull out survivors, and the dead, from beneath the rubble two days after the northwestern city of Herat and its surrounding regions were struck by a deadly earthquake.

The Taliban administration said at least 2,400 people were killed and many more injured in the quakes, which were among the world's deadliest this year after tremors in Tükiye and Syria, in which an estimated 50,000 people were killed.

Neighbors Pakistan and Iran have offered to send rescue workers and humanitarian aid, while China's Red Cross Society offered cash relief aid. A technical team from Iran has arrived in the area, Mullah Janan Sayeeq, spokesman for the Disaster Management Ministry, said during a press conference.

"I ask all countries, to help us in this crucial time," said Sayeeq.

He said rescue operations are ongoing, adding that people are still trapped under rubble in two villages and teams are working to pull them out.

The spokesman of Herat's governor, Nissar Ahmad Elyias, told Reuters that over a dozen villages around Herat were also affected.

Many buildings in Herat city were relatively unaffected, but the medieval minarets of its famous mosques sustained some damage, photographs on social media showed.

"Many of our family members have been martyred, including one of my sons, and my other son is also injured," Herat resident Mir Ahmed told Reuters at a hospital treating many survivors.

"Most of the people are under the rubble."

Hemmed in by mountains, Afghanistan has a history of strong earthquakes, many in the rugged Hindu Kush region bordering Pakistan.

Death tolls often rise when information comes in from more remote parts of a country where decades of war have left infrastructure in shambles, and relief and rescue operations difficult to organize.

In a statement late on Sunday, the U.N. Humanitarian Office put the death toll from the quakes at 1,023, with an additional 1,663 people injured, and more than 500 missing. It said all the homes in the Zindajan district in Herat were destroyed.

Afghanistan's health care system, reliant almost entirely on foreign aid, has faced crippling cuts in the two years since the Taliban took over and much international assistance, which had formed the backbone of the economy, was halted.

Diplomats and aid officials say concerns over Taliban restrictions on women and competing global humanitarian crises are causing donors to pull back on financial support. The government has ordered most Afghan female aid staff not to work, although with exemptions in health and education.

Pakistan said its disaster management authority had put a search and rescue team on standby to assist in the disaster-hit area. It is also preparing to send in relief items including food, medications, tents, and blankets.

Iran, whose border is less than 90 kilometers (56 miles) from the site of the worst-hit area, also pledged humanitarian aid, the Taliban administration said.
