Kabul: In July more than 1,500 civilians were killed or injured during the conflicts, the UN mission said on Saturday.
July saw the highest number of casualties in Afghanistan in a single month since 2017.
"As peace efforts have intensified in recent weeks, so too has the conflict on the ground," said the UN Secretary-General's Special Representative for Afghanistan, Tadamichi Yamamoto.
"I call on all parties not to ramp up military operations thinking that doing so will give them a stronger position in talks about peace. Escalating the conflict will have one primary result: greater loss of civilian life. Now is the time to demonstrate restraint and real respect for the lives of ordinary Afghan civilians," he said.
