A MAJOR security alert was underway along the border yesterday following an increase in dissident republican activity in the area.
Two vehicles were hijacked on Friday and set alight at a railway crossing in Lurgan, Co Armagh. It is believed up to 30 people were involved in the disturbances, which also saw five vehicles hijacked on Thursday night. The violence began after three local dissident republicans were jailed for plotting to kill police officers.
