KYIV: When Russian President Vladimir Putin invaded Ukraine on Feb. 24 in an unprovoked act of aggression, many expected a quick victory.
Six months later, the largest military conflict in Europe since World War II has turned into a grinding war of attrition. The Russian offensive has largely bogged down as Ukrainian forces increasingly target key facilities far behind the front lines, including in Russia-occupied Crimea.
A look at where things stand:
A BOTCHED BLITZ
When Putin declared the start of the special military operation, he urged Ukraine's military to turn against the government in Kyiv, reflecting the Kremlin's belief that the population would broadly welcome the invaders. Some of the Russian troops coming in from Moscow's ally of Belarus, just 200 kilometers (about 125 miles) north of the capital, reportedly brought their parade uniforms with them in preparation for a quick triumph.
Those hopes were quickly shattered by fierce Ukrainian resistance, backed by Western-supplied weapons systems to the government of President Volodymyr Zelenskyy.
Airborne troops sent to seize airfields around Kyiv suffered heavy losses and armored convoys stretching along the main highway leading to the capital were pummeled by Ukrainian artillery and scouts.
Despite numerous attacks on Ukrainian air bases and air defense assets, the Russian air force has failed to win full control of the skies and suffered heavy losses, limiting its ability to support ground forces.
One month into the war, Moscow pulled its troops back from areas near Kyiv, Kharkiv, Chernihiv and other major cities in a tacit acknowledgment of the blitz's failure.
The Kremlin then shifted its focus to the Donbas, Ukraine's eastern industrial heartland, where Moscow-backed separatists had been fighting government troops since 2014 following Russia's annexation of the Crimean Peninsula.
Relying on their massive edge in artillery, Russian forces inched forward in ferocious battles that devastated the region. The strategic port of Mariupol on the Sea of Azov that became a symbol of Ukrainian resistance fell in May after a nearly three-month siege that reduced the city to ruins.
More than 2,400 Mariupol defenders who holed up at the giant Azovstal steel mill later surrendered and were taken prisoner. At least 53 of them died last month in an explosion at a prison in eastern Ukraine that Moscow and Kyiv blamed on each other.
The Russians have taken control of the entire Luhansk region, one of two provinces that make up the Donbas, and also seized just over half of the second, Donetsk. Russia currently occupies about 20% of Ukraine's territory.
Putin will try to bite one piece of Ukrainian territory after another to strengthen his negotiating stand, said Mykola Sunhurovskyi, a military analyst with the Kyiv-based Razumkov Center think-tank. His message to Ukraine is: If you don't sit down for talks now, things will get worse and we will take even more of your territory and kill even more of your people. He's trying to raise not only external but also internal pressure on the Ukrainian government.
The Donbas offensive has slowed as Moscow was forced to relocate some of its troops to Russia-occupied areas in the south to fend off a potential Ukrainian counteroffensive.
Russian troops seized the Kherson region, north of Crimea, and part of the neighboring Zaporizhzhia region early in the conflict. It has installed pro-Moscow administrations there, introduced its currency, handed out Russian passports and launched preparations for referendums to pave the way for their annexation.
But Ukrainian forces recently reclaimed some ground, striking bridges and targeting munitions depots.
Meanwhile, both sides have traded accusations of shelling the Russia-occupied Zaporizhzhia nuclear power plant, Europe's largest, raising fears of an atomic disaster.
Ukraine has forced Russia to conduct a massive redeployment of forces and spread them all along the front line, from Kharkiv to Kherson, said Ukrainian military expert Oleh Zhdanov. It's very hard to stretch them along such a big distance.
Although Kyiv doesn't have enough weapons to launch a big counteroffensive, time plays in Ukraine's favor, he said. The longer the pause lasts, the more weapons Ukraine will receive from its allies.
Western weapons, including U.S. HIMARS multiple rocket launcher s, have boosted Ukraine's military's capability, allowing it to target Russian munitions deports, bridges and other key facilities with precision and impunity.
In a major symbolic victory in April, the flagship of Russia's Black Sea Fleet, the Moskva missile cruiser, exploded and sank while on patrol after reportedly being hit by a Ukrainian missile. That dealt a heavy blow to Russia's pride and forced it to limit naval operations....
