A When US forces are involved ...
According to the BBC News site 'The US-led coalition has admitted its planes carried out an attack in eastern Syria that the Russian army says killed at least 62 Syrian troops fighting IS.
The US said its planes halted the attack in Deir al-Zour when informed of the Syrian presence and would not knowingly strike them.
The strikes allowed IS jihadists to advance, the Russians said.
Russia earlier said the current ceasefire in Syria was in danger of collapse and the US would be to blame.
The cessation of hostilities does not include attacks by the US on IS or other jihadist groups.
