(Reuters) - Russian forces carried out sustained attacks on the eastern Ukrainian city of Bakhmut in their quest for a breakthrough in the year-long war, although one U.S. official predicted few short-term territorial gains for Russia.
DIPLOMACY
* The International Criminal Court has a "historic" role to play in bringing justice for crimes committed in the war in Ukraine and ensuring long-term security, President Volodymyr Zelenskiy said on Tuesday after meeting with the ICC's top prosecutor.
* Colin Kahl, the U.S. under secretary of defense for policy, described the front line in Ukraine as a "grinding slog" and said he did not expect Russia to be able to make significant territorial gains in the near term.
* Ukraine has sent an appeal to the UN and Turkey to start negotiations on extending a grain export deal, but there has been no response, a Ukrainian government source said.
* The Kremlin repeated its position that Russia was open to negotiations to end the Ukraine conflict, but that new "territorial realities" could not be ignored.
* The United States will not hesitate to target China's companies and individuals with sanctions if it violates U.S. sanctions on Russia over the war, Secretary of State Antony Blinken said.
* Foreign ministers from around the world meet in New Delhi this week in the shadow of the war and U.S.-China tensions.
FIGHTING
* Russian President Vladimir Putin told the FSB domestic security service to step up its activity to counter what he said was increasing espionage and sabotage against Russia by Ukraine and the West.
* A drone crashed near a natural gas distribution station southeast of Moscow on Tuesday in an apparent failed attack 110 km from the Russian capital, the regional governor said.
* A hacking attack caused some Russian regional broadcasters to put out a false warning urging people to take shelter from an incoming missile attack, the emergencies ministry said.

* Russia and the United States bickered over whether Russian fertilizer could be donated to Syria as Moscow heightens complaints about obstacles to its fertilizer shipments before the renewal of a deal allowing Ukraine Black Sea grain exports.
