because big countries and Russia and U.S.A are killing Muslim people for a several years and destroying their houses, many of innocent people were killed and now tortured people are trying  to repay for this.

I am not Muslim, but if someone will touch my family or people, i love, i willnot stay calmly. i will defend them or will repay  them as bitterly as be possible.

i think main reason of these act of terrorisms are Russian and U.S.A government
