(BBC) – Chad’s military says it has carried out airstrikes in neighbouring Nigeria on suspected positions of militant Islamist group Boko Haram.
The strikes were in response to the “cowardly and barbaric” bombing of Chad’s capital, N’Djamena, on Monday, it added in a statement.
The group suffered heavy casualties and six of its bases were destroyed, the military said.
However, Nigeria’s military has said the strikes were not on its territory.
In a statement, it said it had identified the targets but the raids probably hit Niger.
“The territory of Nigeria has not been violated,” it said.
