What is going on in Ukraine

 "Russia’s Defense Ministry said that it was using “high-precision weapons” to disable military infrastructure, air defense facilities, military airfields and Ukrainian army planes, Russia’s state-run RIA Novosti news agency reported. But the ministry said it was not attacking cities, and promised that “the civilian population is not at risk.”

The Ukrainian authorities said that invading naval forces were coming ashore at multiple points, including in Odessa and the southern city of Kherson. Three emergency workers were injured when a command post was struck by shelling in Nizhyn, in the north, and six people were trapped under rubble when the city’s airport came under attack, Ukraine’s Interior Ministry reported.

Military depots, warehouses and National Guard were hit with artillery blasts, the ministry said.
As dawn broke in Kyiv, Mr. Zelensky of Ukraine said he had declared martial law. The country’s defense minister told citizens that the army was “fending off enemy forces” and “doing everything it can to protect you.”

But the army was under siege. In the east, Russia-backed separatists — their ranks bolstered by the arrival of hundreds of Russian mercenaries in recent days, according to European officials — said they were hammering Ukrainian troops along the entire 250-mile front line that has divided the rebels and Ukrainian forces since 2014.

Seeking to capture the entire territories of Donetsk and Luhansk, which Mr. Putin recognized as independent on Monday, the rebels were “using all weapons at their disposal,” the Russian news media reported. Ukrainian officials said the attacks included artillery strikes

Ukraine’s state border service reported that Russian troops stationed in Belarus, north of Ukraine, had launched an attack with support from the Belarusian military. Russia had deployed as many as 30,000 troops to Belarus for exercises this month that the United States warned could provide cover for an attack against Kyiv, which lies a fast 140-mile drive away from a main border crossing.

By midmorning in Kyiv, Russia’s Defense Ministry said it had disabled all of Ukraine’s air defenses and air bases."
