Updated: 3 November 2026. The security situation can change quickly; check official and local advice before travelling.
A river separates the Thai village of Mae Sam Laep from Myanmar. On 31 October, it did not separate the people living there from the effects of the war.
Thai officials say blast waves and fragments from a Myanmar military airstrike across the Salween River damaged about 17 homes and public buildings in the Mae Hong Son border community. The subdistrict health centre, a child development centre and places of worship were among the buildings affected, according to officials who inspected the village the following day (The Nation, 2 November).
The attack targeted a position held by the Karen National Union (KNU) on the Myanmar side. There is nothing in the inspection report to suggest that the Thai health centre was itself the intended target. For families living nearby, that distinction does not make broken windows or the fear of another strike any easier to live with.
A new warning for Mae Sam Laep
On 3 November, the head of the local administration warned residents of possible further airstrikes near the border. The warning followed information received from the KNU on the evening of 2 November; the locations of any possible attack were unknown.
Residents were urged to stay calm, remain alert and shelter indoors. Some moved out of their riverside homes to stay overnight with relatives farther from the border, while Thai rangers stepped up 24-hour surveillance and boat patrols on the Salween, according to local reporting. A warning of a possible attack is not confirmation that another strike has taken place (The Nation, 3 November).
The earlier blast had already disrupted ordinary life. Shops along the river closed and boat services at Mae Sam Laep were temporarily suspended. The local administration prepared a school as an emergency refuge, and some families with children and older relatives spent the night away from the river. These are not abstract border-security measures: they are decisions about where to sleep, how to reach care and whether it is safe to open a shop.
Why is there fighting near the border?
Myanmar has been in civil war since its military seized power in a coup in February 2021. The conflict involves the military and a range of resistance forces and ethnic armed organisations. Some of that fighting is taking place close to Thailand, including in Kayin, also known as Karen State.
The KNU says the 31 October attack struck its base opposite Mae Sam Laep and was intended to disrupt supply routes and cross-border trade serving its forces. The group also says Myanmar’s military had earlier warned Thai officials and traders, in a letter sent on 31 August, against moving goods through a crossing it controls. Those are the KNU’s accounts of the warning and the strike’s purpose, not independently established facts (Khaosod English, 1 November).
The war has caused far greater destruction inside Myanmar. Reuters reported on 2 November that an ethnic armed group, an aid worker and rights monitors said military strikes had hit a maternity clinic in Rakhine State and a school in Kayah State over the weekend. Those places are far from the incident across from Mae Sam Laep and should not be treated as one attack (Reuters, 2 November).
Where should travellers be careful?
Mae Sam Laep and the nearby Salween River border area: Given the damage and the local warning, I would avoid non-essential visits to the immediate riverside area. This is my practical recommendation based on the reported situation, not a claim that the province is under a new national travel ban. If you are already there, follow instructions from local officials and your accommodation.
Mae Sot and the border opposite Myawaddy: Thailand’s National Security Council chief has also addressed concerns about the situation in Myanmar’s Myawaddy township, opposite Mae Sot in Tak province. Thai PBS reported on 3 November that Thailand had reinforced border security, sent formal protests and prepared evacuation plans for high-risk border zones. Check local conditions and crossing arrangements before making plans (Thai PBS World, 3 November).
Inside Myanmar: Sweden’s Ministry for Foreign Affairs advises against all travel to Myanmar. The UK advises against all travel to several Myanmar border areas, including Kayin and Kayah states, and says there are active military operations involving airstrikes and artillery. These are advisories for Myanmar; they are not the same as advice for the Thai side of the border (Sweden Abroad, UK advice for Myanmar).
The UK’s Thailand advice describes the security situation in Myanmar as unpredictable and liable to change without notice. Check your route with local authorities, your embassy and your insurer. Do not approach an active incident to take photographs, and do not assume a border crossing or river service is running because it was open yesterday (UK advice for Thailand).
Mae Hong Son is a large province. The warning concerns particular border communities; it would be misleading to describe every destination in the province, or Thailand as a whole, as an active combat zone.
Protests and talks are not yet an agreement
Thailand has raised its concerns with Myanmar through diplomatic and military channels. Thai PBS reported that Thailand’s Chief of Defence Forces met Myanmar’s military attaché, who pledged to coordinate with troops on the ground. The local leader in Mae Sam Laep has called for a halt to operations near the border and a safety zone. These are reported contacts and proposals; no agreed safety zone or ceasefire has been announced (Khaosod English, 2 November).
There is also a wider diplomatic track. On 23 October, Thailand’s foreign minister told Reuters that Bangkok welcomed US engagement with Myanmar’s military-backed government. US and Myanmar representatives had held talks in Tokyo earlier that month, and he expected Myanmar to be discussed at the November ASEAN summit in Manila. He said it was unclear whether the summit would address restoring Myanmar’s full representation (Reuters, 23 October).
For border families, the measure of any conversation will be whether it makes their homes, schools and health services safer. Until then, anyone planning to visit the affected areas should check the latest advice shortly before departure.
