A ceasefire between Thailand and Cambodia appeared shaky but remained in place Tuesday as tensions lingered despite a truce agreement to end deadly border clashes following economic pressure from the U.S. The ceasefire reached in Malaysia was supposed to take effect at midnight on Monday, but was quickly tested. Thailand's army accused Cambodia of launching attacks in multiple areas early Tuesday, but Cambodia said there was no firing in any location.

While some spillover had been anticipated in the hours immediately after the ceasefire took effect, a Thai government statement late Tuesday said that a new clash had broken out at at one of the locations where there had previously been heavy fighting. The Thai army reported exchanges of gunfire into Wednesday morning but said there was no use of heavy artillery.

Jirayu Houngsub, a spokesperson for the office of Thailand prime minister, said in a text message to journalists that the Thai military 'is currently responding and controlling the situation' at Phu Makhuea, a mountain in a disputed area next to Thaikand's Sisaket province. Thailand's army had said the morning fighting stopped after military commanders along the border from both sides met. They agreed to halt troop movements, avoid escalation and establish coordination teams before a joint border committee meeting in Cambodia on Aug. 4, army spokesman Major Gen. Winthai Suvaree said.
