The game was played in unusual circumstances, with both teams assured of making the semi-finals, due to the Cook Islands and Vanuatu unfortunately having to pull out of the tournament during the week.

"Vanuatu's next match day is in the next two days, and VFF do not have sufficient time to replace the players and officials ... The current circumstances are beyond their control," the country's governing body said in a statement.

Under the Ministry of Public Health regulations for the State of Qatar Healthcare Protocol, the positive cases must isolate for a minimum period of seven days, reports RNZ Pacific.

The so-called Doha agreement was signed in February 2020 and set a date for the US to withdraw its troops.

Gen Frank McKenzie said the deal had a "really pernicious effect" on the Afghan government and military.

Defence Secretary Lloyd Austin agreed, saying the agreement had helped the Taliban get "stronger".

In addition to setting a withdrawal date, the Doha agreement included broad obligations on the Taliban to take steps to prevent groups such as al-Qaeda from threatening the security of the US and its allies.
