Reuters: Chad says it bombs Boko Haram bases in Nigeria; Nigeria denies it
* Air strikes cause heavy damage, say Chad authorities
* Nigeria denies attacks took place in its territory
* 38 civilians killed in Boko Haram raid in Niger (Updates Niger death toll, adds Niger govt statement)
N'DJAMENA, June 18 (Reuters) - Chad's military said it had carried out air strikes against Boko Haram bases in Nigeria in retaliation for twin suicide bombings in Chad this week that killed at least 34 people, but the announcement was strongly rejected by Nigeria.
The air raids caused heavy human and material damage to six of the Islamist militants' bases, Chad's military said late on Wednesday, without providing further details.
Nigerian authorities denied reports that the attacks had taken place on its soil, saying they were likely to have instead hit targets in neighbouring Niger.
