KABUL: Taliban insurgents control an estimated 65% of Afghan territory, after making rapid advances against local forces who are largely fending for themselves as foreign troops withdraw.

Following are some of the major milestones in the fighters movement's advance in recent months. Other deadly attacks occurred, some blamed on the Taliban and some on other jihadist groups including an offshoot of Islamic State.

Talks between the Taliban and the Afghan government on a political understanding that could lead to a peace deal, backed by the United States and its allies, have failed to make significant progress.

- April 14 - President Joe Biden announces U.S. troops will withdraw from Afghanistan starting on May 1 and ending on Sept. 11, bringing America's longest war to a close. It was an extension of the previous withdrawal deadline of May 1 agreed between the United States and the Taliban.

- May 4 - Taliban fighters launch a major offensive on Afghan forces in southern Helmand province. They also attack in at least six other provinces.

- May 11 - The Taliban capture Nerkh district just outside the capital Kabul as violence intensifies across the country.

- July 2 - American troops quietly pull out of their main military base in Afghanistan - Bagram Air Base, an hour's drive from Kabul. It effectively ends U.S. involvement in the war.

- July 5 - The Taliban say they could present a written peace proposal to the Afghan government as soon as August.

- July 21 - Taliban insurgents control about a half of the country's districts, according to the senior U.S. general, underlining the scale and speed of their advance.

- July 26 - The United States vows to continue to support Afghan troops "in the coming weeks" with intensified airstrikes to help them counter Taliban attacks.
