Calm held for a second straight day along the Cambodia-Thailand border on Sunday after the two sides reached a cease-fire agreement, Cambodian defense officials said.

Speaking at a news briefing, Defense Ministry spokesperson Lt. Gen. Maly Socheata said the situation on the frontline has remained stable since noon Saturday, when the cease-fire took effect, state-run Agence Kampuchea Presse reported.

The Thai military also confirmed that violence had subsided, although some movement was observed in certain locations, according to Thai media outlet Khaosod.

The two Southeast Asian countries signed a cease-fire agreement Saturday, ending nearly 20 days of clashes that killed dozens and displaced almost 1 million civilians along their disputed border.

Under the agreement, the sides committed to an immediate halt to all hostilities involving any weapon and pledged to avoid unprovoked fire, troop advances, or movements toward each other’s positions.
