PRISTINA (AFP) - NATO said Tuesday it has asked for troop reinforcements for its mission in Kosovo days after a trade row with Serbia sparked deadly violence in the volatile north. "We have asked for one battalion," Hans Dieter Wichter, a spokesman for NATO's KFOR force, told AFP. A battalion is usually around 500 soldiers and a German military spokesman told AFP in Berlin that the reinforcements would be sent from Germany and Austria. Wichter said the extra troops were needed to boost the operational reserve of the more than 5,900 KFOR soldiers currently in Kosovo as "all of them are currently deployed". He stressed that the request did not mean that KFOR was unable to control the situation in northern Kosovo, where unrest flared last week after the ethnic Albanian government ordered police to seize control of two border crossings.
