**Rebels in Senegal have killed six soldiers in the south of the country, the military says.**The attack occurred in the Casamance region, which has a long history of separatist violence.
The soldiers were killed by a rocket-propelled grenade after their vehicle became stuck in mud near the border with Guinea-Bissau, the army says.
There has been an increase in violence in Casamance in recent months, despite a peace accord signed in 2004.
No group has said it carried out the latest attack.
An army spokesman, Capt Moussa Coulibaly, told the BBC he believed rebels from the Casamance Movement of Democratic Forces (MFDC) were responsible.
BBC West Africa correspondent Caspar Leighton says the recent upsurge in violence has been blamed on MFDC dissidents which have rejected the peace accord.
The MFDC started a war for regional independence in 1982.
Because of its natural beauty Casamance has traditinally been a popular tourist destination, but despite the peace accord many have stayed away.
