MOSCOW — The Kremlin said on Monday that the United Kingdom's decision to hand Ukraine information on British-made components used to make SCALP long-range missiles would "add fuel to the fire" and was regarded by Moscow extremely negatively.

UK Prime Minister Andy Burnham arrived in Kyiv on Monday on his first overseas trip since taking office and was due to announce British support to help Kyiv improve its domestic production of long-range missiles.

Asked about the visit and the support, Kremlin spokesman Dmitry Peskov accused the UK of doing everything it could to prevent any progress toward an eventual peace deal.

"Britain methodically and regularly adds fuel to the fire and methodically and regularly hatches schemes to prevent even the slightest progress in the peaceful settlement process," Peskov told reporters.
