Four US-led soldiers were killed in a bomb explosion in the southern Afghanistan province of Kandahar on Saturday, the force said in a statement.
  
Two more soldiers were badly wounded in the incident in the restive province where dozens of Taliban were killed in an massive operation by Afghan and foreign troops last week.
  
"Four coalition service members were killed and two more were seriously wounded today in an IED (improvised explosive device) strike while conducting operations in Kandahar province," the statement said.
  
The nationalities of the troopers was not revealed.
  
The incident came a day after two other US-led soldiers were killed in separate incidents including a suicide bombing elsewhere in the country.
  
The latest deaths took to 31 the number of international soldiers killed in Afghanistan since the start of this month, the deadliest month for the foreign military deployment this year. More than 20 troopers died last month.
  
With the latest casualties 98 foreign troopers have died in Afghanistan this year, according to an AFP tally based on official figures.
  
Kandahar was the birth place of the Taliban, the main militant group behind a spiraling insurgency, and last week it saw a massive operation by Afghan and foreign troops against Taliban guerrillas.
  
Dozens of rebels were killed during the operation in Arghandab, a district near the city where about 500 Taliban gathered following a mass breakout from the city's main prison.
