Zelenskiy visits Kupiansk as Ukrainian forces retake parts of the town, encircling Russian troops. Kyiv denies Russian claims of advances.

KYIV, Dec 12 (Reuters) - Ukrainian forces said they had retaken parts of the northeastern town of Kupiansk and had encircled Russian troops there as President Volodymyr Zelenskiy visited the area and praised the operation, saying it strengthened Ukraine diplomatically.
With U.S.-backed peace efforts underway, Moscow has said it is advancing on all fronts and that it has seized Kupiansk and the strategic city of Pokrovsk in the east. Kyiv has denied this, saying that the fighting is continuing.
In a video clip posted on his social media account on Friday, Zelenskiy, wearing a bulletproof vest, is seen standing in front of a sign bearing the town's name at the entrance to Kupiansk.
"Today it is extremely important to achieve results on the front lines so that Ukraine can achieve results in diplomacy," Zelenskiy said in the clip.
RUSSIANS IN KUPIANSK 'COMPLETELY CUT OFF', KYIV SAYS
Ukraine's Khartiia Corps of the National Guard said it had liberated several northern districts of Kupiansk.
Russian supply routes have been cut off and several hundred Russian troops are surrounded, Khartiia said on the Telegram messaging app.
Reuters could not immediately verify the battlefield reports.
"Today, we can say that the Russians in the city are completely cut off. For a long time, they couldn't understand what was happening. But now they know they are surrounded," Ihor Obolienskyi, Khartiia's commander, was quoted by the Ukrainska Pravda news outlet as saying.
Russia, which began its full-scale invasion of Ukraine in February 2022, did not immediately comment on the Ukrainian assertions.
Ukraine's Deep State battlefield mapping project now shows at least three villages to the north and west of Kupiansk under Ukrainian control.
Kupiansk's northern districts are also shown as being under Ukrainian control, and the map suggests Russian troops are encircled in the city centre.
Military analysts said that in November, the pace of Russian advances had picked up to its highest this year as troops moved forward, taking control of smaller villages.
Russia said on Thursday it had captured the eastern town of Siversk. Kyiv said it remained under Ukrainian control.
