UN Secretary-General Antonio Guterres has met with people displaced by the Afghan conflict after arriving in Kabul on a surprise visit.
All parties in the conflict should come together because "this is a war that has no military solution," Guterres said on the outskirts of Afghanistan's capital on June 14.
"We need to have a political solution, we need to have peace," he added.
After landing in Kabul earlier in the day, Guterres wrote on Twitter that the UN "stands with Afghanistan at a time of violence and suffering."
Guterres's visit comes after a truck bombing killed more than 150 people in Kabul on May 31 in the deadliest attack in the Afghan capital since the ouster of the Taliban following the U.S.-led invasion in 2001.
The UN secretary-general arrived in Kabul following a Central Asian tour during which he visited Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan.
UN Undersecretary-General Jan Kubis traveled to Kabul earlier this week "in the interest of completing a Security Council-requested strategic review" of the UN Assistance Mission in Afghanistan (UNAMA) and its work, UNAMA said.
