Shell hits bus in eastern Ukraine, kills ten

A shell has hit a bus in eastern Ukraine, killing at least 10 civilians and wounding many more, Ukraine's military says.

A statement said the incident happened at a government checkpoint in Buhas, about 35km south-west of the rebel stronghold of Donetsk. One report said the bus had been carrying civilians from the coastal town of Mariupol.

Donetsk regional officials blamed pro-Russian rebels but a report said rebel leaders had denied it.

Fighting has intensified recently, despite a truce agreed in September.

A statement by the military said it was believed the missile had been fired from a Grad multiple rocket launcher. However, the Russian news agency Tass quoted rebel officials denying they had carried out the attack.
