Kabul: The Taliban seized a radio station in Kandahar and took to the airwaves Saturday after capturing much of southern Afghanistan in a rapid offensive that has raised fears of a full takeover less than three weeks before the US is set to withdraw its last troops.

The Taliban have captured much of northern, western and southern Afghanistan in recent weeks, leaving the Western-backed government in control of a smattering of provinces in the center and east, as well as the capital, Kabul, and the northern city of Mazar-i-Sharif.

The withdrawal of foreign forces and the swift retreat of Afghanistan's own troops _ despite hundreds of billions of dollars in US aid over the years _ has raised fears the Taliban could return to power or the country could be plunged into civil war.

The first Marines from a contingent of 3,000 arrived on Friday to help partially evacuate the US Embassy. The rest are set to arrive by Sunday, and their deployment has raised questions about whether the administration will meet its Aug. 31 withdrawal deadline.

Smoke rises after fighting between the Taliban and Afghan security personnel in the city of Kandahar. The Taliban released a video in which an unnamed insurgent announced the takeover of the city's main radio station, which has been renamed the Voice of Sharia, or Islamic law.

All employees were said to be present and would broadcast news, political analysis and recitations of the Quran, the Islamic holy book. It appears the station will no longer play music.

It was not clear if the Taliban had purged the previous employees or allowed them to return to work. Most residents of Kandahar sport the traditional dress favored by the Taliban. The man in the video congratulated the people of Kandahar on the Taliban's victory.

The Taliban have operated mobile radio stations over the years, but have not operated a station inside a major city since they ruled the country from 1996-2001. At that time, they also ran a station called Voice of Sharia out of Kandahar, the birthplace of the militant group. Music was banned.

The US invaded shortly after the 9/11 attacks, which al-Qaida planned and carried out while being sheltered by Taliban. After rapidly ousting the Taliban, the US shifted toward nation-building, hoping to create a modern Afghan state after decades of war and unrest.

Earlier this year, President Joe Biden announced a timeline for the withdrawal of all US troops by the end of August, pledging to end America's longest war. His predecessor, President Donald Trump, had reached an agreement with the Taliban to pave the way for a US pullout.

The Taliban, who have long controlled large parts of the Afghan countryside, moved quickly to seize provincial capitals, border crossings and other key infrastructure. They are now within 80 kilometers (50 miles) of Kabul.

The group had previously governed Afghanistan under a harsh version of Islamic law in which women were largely confined to the home.
