Tension accelerates in Europe

Tensions have accelerated following a Russian drone strike on a passenger train near the Poland-Ukraine border just moments after former UK Prime Minister Boris Johnson and other European security officials passed through.
No casualties were reported after the strike at Yahodyn, which hit the train's engine. All the passengers had been evacuated, Ukrainian authorities said. 
Johnson and other European national security advisers, including the UK's Jonathan Powell, had passed along the same line on a different train on their way back from a conference in Kyiv.
Russia's defence ministry said it had struck "railway infrastructure" in western Ukraine, but Ukraine's state railway company Ukrzaliznytsia said the drone's target "could have been the diplomatic train".
The Kremlin said on Monday it would keep striking targets across the "whole" of Ukraine, when asked about a rare drone attack on the Polish border that has rattled Warsaw and its European allies.
"If I understand correctly, this is about Ukrainian territory," Kremlin spokesman Dmitry Peskov said, when asked by AFP about the strikes.
"Our military are fulfilling their tasks on the whole territory of Ukraine... They will continue to do so," he added.
Meanwhile, the office of UK Prime Minister Andy Burnham said Monday that Russian strikes on the train were aimed at undermining international support but Britain would not be deterred.
A spokesperson for his Downing Street office told journalists the attack on a Warsaw-bound train close to the Polish border "was a futile attempt by Russia to undermine our support for Ukraine. It will not deter us". 
German Chancellor Friedrich Merz said on Monday that Europe was facing decisive weeks and months ahead in terms of "defending the freedom and peace of our continent" against Russia.
"I will do everything I can to keep up our support and to get people convinced that this is in our own interest to do that," said Merz, speaking at a press conference in Finland.  

NATO chief Mark Rutte said Monday that the strike by Russia on the Warsaw-bound train would not put off Kyiv's Western backers.
"The strike on a passenger train in Ukraine yesterday shows how desperate (Russian President Vladimir) Putin has become. He thinks that he can stop us from supporting Ukraine and that he can undermine our unity. He is wrong. Our answer is to increase support," Rutte told journalists. The EU's top diplomat said Monday that Russian strikes were meant to "scare" off Kyiv's backers.
"It is clearly meant to scare Western countries from supporting Ukraine, from going to Ukraine to show support," foreign policy chief Kaja Kallas said, urging Kyiv's backers to do "the opposite".
On the other hand, the Kremlin said the leaders of China and India had told President Vladimir Putin that they stood ready to help end the conflict in Ukraine and that Putin had reacted very positively to the suggestion.
Kremlin spokesman Dmitry Peskov said the discussion had happened on the sidelines of the BRICS summit in New Delhi and that Russia was open to any country using its influence to encourage Kyiv to show "greater flexibility."
US President Donald Trump on Sunday called on Ukrainian President Volodymyr Zelenskiy to stop targeting Russian diesel infrastructure, saying the attacks were causing a shortage of the fuel that is "hurting the world".
"Mr Zelenskiy has to do one thing: He has to stop knocking out diesel fuel in Russia," Trump told journalists during a visit to the Irish Open, which is being held in the west of Ireland on a golf course owned by his family.
