N Korea's Kim unveils 50 rocket launchers ahead of key congress North Korean leader Kim Jong Un has unveiled dozens of nuclear-capable rocket launchers ahead of a key congress of the governing Workers' Party, according to state media. Kim hailed the 600mm-calibre rocket launchers as "wonderful" and "attractive" during the ceremony on Wednesday, adding that new military and construction goals will be set during the upcoming congress. "When this weapon is used, actually, no force would be able to expect God's protection," Kim said, according to the KCNA "It is really a wonderful and attractive weapon," Kim said, according to South Korea's Yonhap News Agency. He described the launchers as the "world's most advantageous weapon for concentrated super-powerful attack", according Yonhap. Photos released by state media showed dozens of launch vehicles parked in neat rows on the plaza of Pyongyang's House of Culture, which will host the congress.

Fragments of a drone lie scattered on the ground in the Muksan-ri area, Kaepung District, Kaesong City, North Korea, after North Korea said on Saturday that South Korea sent another drone into North Korean airspace on Jan. 4, according to North Korean state media KCNA, in this picture released on Jan. 10. SEOUL - South Korea's Unification Minister Chung Dong-young said on Wednesday that three civilians had sent drones to North Korea on four occasions since President Lee Jae Myung took office last year, harming inter-Korean ties. The trio flew the aircraft between September and January, Chung said, citing an ongoing investigation by police and the military. Drones crashed on two occasions in North Korea, in line with claims made by Pyongyang, he said. On two other attempts the drones returned to Paju, a border settlement in South Korea, after flying over Kaesong, a city in North Korea, Chung said.

Could Ukraine hold a presidential election right now? Will Europe use frozen Russian assets to fund war? How can Ukraine rebuild China ties? 'Ukraine is running out of men, money and time' More than 1,300 apartment buildings in the Ukrainian capital, Kyiv, were still without heating following Russia's missile and drone attacks on Saturday, according to Mayor Vitalii Klitschko. Over the past week alone, Russia launched more than 1,700 attack drones, at least 1,380 guided aerial bombs, and 69 missiles on Ukraine, mainly targeting the energy sector, critical infrastructure, and residential buildings, according to Ukrainian President Volodymyr Zelenskyy.

Since September, residents on South Korea's Jeju island have been spotting small packs of what appear to be bags of Chinese tea washed ashore. Upon closer inspection, however, they were found to contain ketamine. Some 28kg (62 lbs) of the drug, wrapped in foil and labelled with the Chinese character for tea, have been found on at least eight occasions, police say. Ketamine is used as an anaesthetic in medical procedures, but its recreational use is illegal in South Korea. It can cause severe physical and mental damage, including to the heart and lungs, when misused.

The history of the Korean language is characterized by a discrepancy between its spoken and written forms and a pivotal shift from Chinese characters to the Hangul alphabet. However, this linguistic evolution has remained largely unexplored in NLP due to a lack of accessible historical corpora. To address this gap, we introduce the Open Korean Historical Corpus, a large-scale, openly licensed dataset spanning 1,300 years and 6 languages, as well as under-represented writing systems like Korean-style Sinitic (Idu) and Hanja-Hangul mixed script. This corpus contains 18 million documents and 5 billion tokens from 19 sources, ranging from the 7th century to 2025. We leverage this resource to quantitatively analyze major linguistic shifts: (1) Idu usage peaked in the 1860s before declining sharply; (2) the transition from Hanja to Hangul was a rapid transformation starting around 1890; and (3) North Korea ' s lexical divergence causes modern tokenizers to produce up to 51 times higher out-of-vocabulary rates. This work provides a foundational resource for quantitative diachronic analysis by capturing the history of the Korean language. Moreover, it can serve as a pre-training corpus for large language models, potentially improving their understanding of Sino-Korean vocabulary in modern Hangul as well as archaic writing systems.

In this paper, we pursue the discrete flow approach of Campbell et al. (2024) and introduce Discrete
