Lithuania just sent soldiers to its border with Kaliningrad.
That's the Russian territory squeezed between Lithuania and Poland.
Martynas Katelynas is Lithuania's Interior Minister. He asked Robertas Kaunas, the Defence Minister, to send troops to help border guards there.
Robertas Kaunas said yes. His order took effect straight away. Troops will reinforce the border over the next few weeks.
Both ministers call it a preventive step. Not a response to anything happening right now. Martynas Katelynas says the border is calm.
So why send troops to a calm border?
Because of what happened just along the frontier in Latvia, two to three days ago. At least 20 migrants tried to cross from Belarus into Latvia. Armed guides in masks led them. They threatened Latvian soldiers.
Hours later, it happened again. Masked people crossed the same stretch of border. They damaged an electrical panel. They stole surveillance cameras. Then they went back into Belarus.
Here's the geography that matters. Lithuania and Latvia both border Belarus, which is a close ally of Russia. And Lithuania also borders Kaliningrad, Russia's heavily militarised exclave sitting between Lithuania and Poland.
Martynas Katelynas says the Latvia incidents are why Lithuania is acting now. He says it is a preventive decision, so Lithuania is ready to stop anything similar happening on its own border.
Robertas Kaunas gave a second reason. He linked the move to what he called mobilisation happening in Russia right now. He said Lithuania needs to prepare for more people crossing the border aggressively.
That's a firmer claim than Katelynas made. Katelynas only said there are signals Russia might announce a mobilisation. Not that one is under way.

And here's the thing. Russia hasn't announced any mobilisation. Neither minister has given evidence that one is happening.
This troop move isn't the only signal from Lithuania this week.
A day before the deployment, Lithuania's parliament took its first step toward lifting a constitutional ban. That ban has kept nuclear weapons and foreign military bases off Lithuanian soil since it was written.
And Lithuania's Prime Minister, Mindaugas Sinkevičius, says Lithuania is ready to pay for a permanent American military base on its own territory. That came after Donald Trump said he'd consider the request.
NATO has been building up the region too. A German military brigade is now permanently stationed in Lithuania. That's the first time Germany has permanently based troops abroad since the Second World War.
Russia has already said what it thinks of a permanent American base in Lithuania. This was two days ago, before the troop deployment.
Dmitry Peskov is the Kremlin's spokesperson. He said a US base there would be seen by Moscow as a step toward escalation. He said it wouldn't help stability. He called it another significant round in the escalation of tensions. And he said Russia would be forced to respond.
So that warning came before Lithuania sent troops to the Kaliningrad border. It was about a future US base, not this deployment. Russia hasn't yet responded to the troop move itself.
The Kremlin has separately warned about Kaliningrad directly. Russia's President, Vladimir Putin, said about a week ago that Russia is ready to use everything it has, including nuclear weapons, to defend Kaliningrad against any NATO attempt to isolate it.
So here's where that leaves things. Lithuania is reinforcing a border Russia has already said it would use nuclear weapons to protect. And it's doing that days after its own lawmakers moved to let nuclear weapons onto Lithuanian soil for the first time.
What we don't know: how many troops are being sent, how long they'll take to arrive, what they're authorised to do if they meet an incursion, and whether this becomes permanent. Neither ministry has said.
For now, both Lithuanian ministers say the border is calm. The troops are going in before anything happens there, not after.
