KABUL (AFP) -- Three NATO soldiers and an Afghan trooper were killed along with several insurgents in Afghanistan, while a helicopter gunship made a forced landing, the alliance said.

The deaths among the troops from the NATO-led International Security Assistance Force bring the number of foreign troops killed in Afghanistan this year to 124. ISAF does not release the nationalities of the soldiers killed before their native country has been notified. ""I can confirm the death of two ISAF soldiers in eastern Afghanistan today (Friday),"" a spokesman in the ISAF headquarters in Kabul said Friday. An official statement from the military force said a third NATO soldier was killed in the south of the country. A second spokesman for the troops in eastern Afghanistan, Stern Berg, said 13 ISAF soldiers were injured in addition to 24 militants who were ""killed or wounded."" ""Two ISAF soldiers and an Afghan army soldier have been killed, 13 ISAF soldiers and a civilian have been wounded in the operation,"" said Berg. The force also said in a press statement that an ISAF AH-64 Apache attack helicopter made a ""precautionary landing"" in eastern Kunar province bordering Pakistan today. ""The helicopter is secured and the crew was safely recovered with no injuries,"" it said. The helicopter carrying a two-man crew was providing support for a medical evacuation of ISAF personnel when the crew made the controlled landing after noting a possible failing engine. ""Insurgent activity was reported in the vicinity where the helicopter was supporting the medical mission,"" it said. An AFP reporter said he could see the helicopter with smoke billowing from its tail, with several medical evacuation helicopter signs flying back from the operation site, apparently evacuating casualties. There are more than 50,000 foreign troops mainly under NATO command in Afghanistan fighting Taleban militants who have waged a bloody insurgency since being ousted from power in late 2001
