NATO leaders at the Brussels summit on Monday agreed to maintain funding for the Hamid Karzai International Airport in Kabul after the Resolute Support mission in Afghanistan ends.

Addressing a press conference after the summit, NATO Secretary General Jens Stoltenberg said the RS mission is ending but NATO will continue supporting Afghanistan in four ways: funding Afghan forces, out-of-country training for Afghan forces, a continued civilian presence, and maintaining "critical infrastructure" such as the Kabul airport.

Amid a sharp rise in fighting, Afghan forces have retaken two districts in the north in the last five days. However, other districts continue to fall to the Taliban.

Khan Abad district in Kunduz was retaken on Monday and Chah Ab district in Takhar was retaken last week.
