Russia's war on Ukraine latest: Ukrainian troops plan counterstrike

* Slovakia has handed over the first four MiG-29 jets it has pledged to donate to Ukraine, with the rest of the planes to be delivered in the coming weeks, the Slovak Defence Ministry said on Thursday. * Hungary would not arrest Russian President Vladimir Putin if he entered the country, Prime Minister Viktor Orban's chief of staff said on Thursday, adding that it would have no legal grounds.

Ukrainian troops, on the defensive for four months, will launch a long-awaited counterassault "very soon" now that Russia's huge winter offensive is losing steam without taking Bakhmut, Ukraine's top ground forces commander said on Thursday. DIPLOMACY

* Finland's defence minister on Thursday said he did not want to donate Hornet fighter jets to Ukraine. "My view as Finland's defence minister is that we need these Hornets to secure our own country," Antti Kaikkonen said. * Slovakia has handed over the first four

MiG-29 jets it has pledged to donate to Ukraine, with the rest of the planes to be delivered in the coming weeks, the Slovak Defence Ministry said on Thursday.

* Hungary would not arrest Russian President Vladimir Putin if he entered the country, Prime Minister Viktor Orban's chief of staff said on Thursday, adding that it would have no legal grounds. * Any attempt to

should be put on trial for the invasion of Ukraine even if they cannot be arrested and brought to court in person, Kyiv's top prosecutor said on Thursday. * EU leaders will discuss the war in Ukraine with U.N. chief

Antonio Guterres on Thursday, including food security and sanctions, and also endorse a plan to ramp up the supply of artillery shells to Kyiv, diplomats and officials said.

* Peace plans and pipelines: What came out of the Putin-Xi talks? * U.S. Secretary of State Antony Blinken said China is "very carefully" watching the global response to the invasion but has not yet crossed the line of providing lethal aid to Moscow.

FIGHTING * Ukrainian President Volodymyr Zelenskiy has visited the southern region of

Kherson , where he toured local infrastructure and promised to "restore everything" following Russia's invasion.

* British military intelligence said on Thursday that Russia had partially regained control over the approaches to the eastern Ukrainian town of Kreminna, after its troops were pushed back from the region earlier this year. * The Russian-backed administration in Sevastopol suspended ferry routes around the Crimean port, shortly after its governor said air defences repelled a Ukrainian drone attack.
