You should have heared about what Taliban may have committed of killing two German hostages, and the threat of killing other 23 South Korean.
That's true that their states may be invaders of your lands, but what is the crime of their citizens?!!!!!
Civilians are out of that game, when they came to your states they didn't come on the backs of tanks, they didn't come by air fighters hitting your homes, they didn't point a gun towards your children, then their is not any justification to threat their safety on your lands.
If Qur'an ordered us about war prisoners of soldiers that " And they feed, for the love of Allah, the indigent, the orphan, and the captive,- " 76:8 so what about civilians, what about women, what about children?!!! Islam don't order to frighten a child, or threaten an innocent woman.
Don't claim always that you are the ones who represent Islam, Muslims don't kill innocents and civilians, or even frighten kids. BUT when their lands are stolen and their innocents are killed and their children are tortured, then they turn into lions against those who commit that, and fight against every soldier who come to their lands on a tank or in an air fighter aiming at stealing their land, or every soldier who point a gun towards their children, women and their civilians.
