Ukraine military claims Russians fired cross-border artillery at them

The Ukrainian army has claimed that its soldiers came under artillery fire from the Russian side of the border overnight and were attacked by rebels in several other places in the country’s restive east. In a statement on Friday, the headquarters of the government’s military operation in the east listed at least seven locations where rebels attacked Ukrainian troops. They also claimed that attacks on two locations including a border crossing were supported by artillery fire from Russia. Moscow has vehemently denied a role in the conflict .

Both Russia and Ukraine say cross-border attacks are taking place, but both say that they are innocent and the other one is guilty.

Meanwhile, international observers from the Organisation for Security and Cooperation in Europe on Friday were travelling to inspect the wreckage of the downed Malaysia Airlines plane and to search for more bodies. Human remains are still being found at the crash site more than a week after the plane went down. U.S. officials say the Boeing 777 was probably shot down accidentally by a missile fired by pro-Russian rebels.
