British military officials say one of their soldiers has been killed in Afghanistan by a suspected member of the Afghan National Army.

Britain's Ministry of Defense said Tuesday the attacker turned his gun on international troops at a base in southern Helmand province and opened fire. Local officials say several other British troops were wounded in the attack.

The NATO command in Afghanistan says the killing Monday is the latest suspected incidence of what officials call “insider attacks.”

“Insider” attacks have been on the on the rise in Afghanistan, leaving more than 60 foreign troops dead in 2012.

Monday's attack also came as Afghanistan's President Hamid Karzai and U.S. President Barack Obama prepared to meet in Washington later in the week for talks on the long-term security agreement between the two nations.

Security in Afghanistan is of rising concern as U.S. and international forces draw down their troops. Most NATO troops are set to depart Afghanistan by 2014. Some U.S. forces are scheduled to remain after that, but details have yet to be worked out.
