Russia’s retreat from the city of Kherson appears to have descended into chaotic scenes amid reports of some units being told to escape any way they could.

Russian forces are believed to have blown up a bridge over the Dnipro River to prevent a Ukrainian pursuit. It was unclear how many Russian troops were still waiting to cross, although the Russian Telegram channel Rybar suggested the retreat was complete.

Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).
LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F); maximum transport pressure is set at around 25 kPa (4 psi) (gauge pressure), which is about one-fourth of atmospheric pressure at sea level.
The gas produced from hydrocarbon deposits typically contains a wide range of hydrocarbon products, which usually includes methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10). All these products have wide-ranging boiling points and also different heating values allowing different routes to commercialization and also different uses. The "acidic" elements such as hydrogen sulphide (H2S) and carbon dioxide (CO2), together with oil, mud, water, and mercury, are removed from the gas to deliver a clean sweetened stream of gas. Failure to remove such acidic molecules, mercury, and other impurities could result in damage to the equipment. Corrosion of steel pipes and amalgamization of mercury to aluminum within cryogenic heat exchangers could cause expensive damage.
The gas stream is typically separated into the liquefied petroleum fractions (butane and propane), which can be stored in liquid form at relatively low pressure, and the lighter ethane and methane fractions. These lighter fractions of methane and ethane are then liquefied to make up the bulk of LNG that is shipped.
Natural gas was considered to be economically unimportant wherever gas-producing oil or gas fields were distant from gas pipelines or located in offshore locations where pipelines were not viable. In the past this usually meant that natural gas produced was typically flared, especially since unlike oil no viable method for natural gas storage or transport existed other than pipelines, which required the immediate use by end users of the same gas. This meant that natural gas markets were historically entirely local and any production had to be consumed within the local network.
Developments of production processes, cryogenic storage, and transportation effectively created the tools required to commercialize natural gas into a global market which now competes with other fuels. Furthermore, the development of LNG storage also introduced a reliability in networks which was previously thought impossible. Given that storage of other fuels is relatively easily secured using simple tanks, a supply for several months could be kept in storage. With the advent of large-scale cryogenic storage, it became possible to create long term gas storage reserves. These reserves of liquefied gas could be deployed at a moment's notice through regasification processes and today are the main means for networks to handle local peak shaving requirements.

Moskva (Russian: Москва, lit. 'Moscow'), formerly Slava (Russian: Слава, lit. 'Glory'), was a guided missile cruiser of the Russian Navy. She was the lead ship of the Project 1164 Atlant class and was named after the city of Moscow. She was the flagship of the Russian Black Sea Fleet and had led Russia's naval assault on Ukraine. With a crew of 510, she was a major symbolic and military asset to Russia.On 13 April 2022, two Ukrainian officials said that Moskva had been hit by Ukrainian R-360 Neptune anti-ship cruise missiles and was on fire in heavy seas. The Russian Ministry of Defence reported the ship was seriously damaged after a fire which caused a munitions explosion. The next day, following an effort to tow her to port, Moskva sank.

The General Framework Agreement for Peace in Bosnia and Herzegovina, also known as the Dayton Agreement or the Dayton Accords, (Croatian: Daytonski sporazum[1], Serbian and Bosnian Dejtonski mirovni sporazum / Дејтонски мировни споразум) is the peace agreement reached at Wright-Patterson Air Force Base near Dayton, Ohio, United States, on 21 November 1995, and formally signed in Paris, on 14 December 1995. These accords put an end to the three-and-a-half-year-long Bosnian War, one of the Yugoslav Wars.
The warring parties agreed to peace and to a single sovereign state known as Bosnia and Herzegovina composed of two parts, the largely Serb-populated Republika Srpska and mainly Croat-Bosniak-populated Federation of Bosnia and Herzegovina.
The agreement has been criticized for creating ineffective and unwieldy political structures and entrenching the ethnic cleansing of the previous war.
