"Kallas is not particularly optimistic about the war in Ukraine: she believes that there are at least two more years of conflict ahead," the publication writes, without providing further quotes.

"El Pais" reports that "in the corridors of Strasbourg" there is talk of a stalemate in the Russia-Ukraine war. The European Parliament is expressing concern that Russia has become much bolder, as evidenced by Wednesday's attack on Poland.

"Interviewed sources predict that the war will last as long as the leaders of both sides do not change," writes El Pais.

Earlier, it was reported that several Russian attack drones entered Polish airspace overnight Wednesday, with those that posed a direct threat being shot down. Polish Prime Minister Donald Tusk said that the country's airspace had been violated 19 times and that at least three drones had been shot down.

NATO countries discussed the drone incident on Wednesday, with Poland invoking Article 4 of the NATO treaty, which provides for consultations between NATO members if any of them believes its territorial integrity, political independence or security is threatened.
