Gunfights and blockades of burning vehicles broke out Friday in the border city of Reynosa, across from McAllen, Texas, leaving at least three dead, Mexican authorities said. The government of the border state of Tamaulipas said federal police and soldiers had "detained members of a criminal gang that operates in Reynosa." "Members of the same criminal group reacted (to the arrests) by attacking federal forces and carrying out blockades in the city," AP quoted the statement as saying. Officials said roads in the city were blocked with vehicles set on fire by gunmen. The state government said three armed civilians, presumably cartel gunmen, had been killed in the confrontations. Authorities said the situation was brought under control by late afternoon. The detained gang members were taken to Mexico City, the state government said.
