(Corrects Ukrainian minister's title to foreign minister in paragraph 4)

By Janis Laizans ‌and Andrius Sytas

RIGA, May 10 (Reuters) - Latvian ‌Defence Minister Andris Spruds resigned on Sunday, after two ​Ukrainian drones on Thursday flew in from Russia and hit oil storage facilities.

Earlier on Sunday, Latvian Prime Minister Evika Silina demanded the resignation, ‌saying anti-drone ⁠systems had not been deployed fast enough. She appointed Latvian army colonel ⁠Raivis Melnis as the new defence minister.

Latvia and Lithuania on Thursday called on NATO to ​boost air ​defences in their ​region after two ‌drones came over the Russian border and exploded at an oil storage facility in Latvia.

Ukrainian foreign minister Andrii Sybiha on Sunday said on X that the drones were Ukrainian, ‌and flew into Latvia as ​a result of "Russian electronic ​warfare deliberately diverting ​Ukrainian drones from their targets ‌in Russia."

In response to the ​drone incidents, ​Ukraine is considering sending experts to help strengthen air security over the Baltic ​states, Sybiha ‌said on Friday.
