A 6.3-magnitude earthquake struck Afghanistan early today near the northern city of Mazar-e-Sharif, according to the U.S. Geological Survey.

The extent of the damage was not immediately clear. The quake struck just before 1 a.m., the USGS reported. Mazar-e-Sharif is a city of about 500,000 people that is known for its magnificent Blue Mosque.

The earthquake is the latest to hit Afghanistan in recent months, including one in late August near the eastern city of Jalalabad that killed at least 1,400 people and injured more than 3,100 others, authorities said.

Four years after the Taliban retook power in Afghanistan, more than half of the country’s 42 million people are already in need of humanitarian assistance. The country has been further strained by the recent return of many jobless Afghans who were deported from Iran or Pakistan.

At the same time, a sharp drop in foreign aid this year has forced the closure of hundreds of health care facilities and left more people without consistent access to food.
