Jhansi, May 17 -- Four people, including a brother and sister, lost their lives in two separate road accidents on the Jhansi-Kanpur highway in Jhansi district within two days. The incidents have once again raised concerns over road safety on the busy highway. In the first accident reported on Saturday morning, 20-year-old Ishu Ahirwar and his 23-year-old sister Shivani were killed after their motorcycle crashed into a truck near the Nandani weighbridge in the Pooch area. The siblings, residents of Dehghua village under Kotwali Jalaun, were travelling to Moth to visit relatives when the accident took place. According to circle officer Ajay Shrotiya, the motorcycle rammed into the rear side of the parked truck, throwing both riders onto the road and leaving them critically injured. Local residents informed the police and helped shift the victims to the community health centre, where doctors declared them dead on arrival. Police later sent the bodies for postmortem examination and started further investigation into the case. In another accident that took place a day earlier near Chirgaon on the same highway, a 45-year-old man and his 28-year-old nephew were killed after a truck hit their motorcycle while they were returning home to Moth. The deceased were identified as Sumit Kumar and Veer Bahadur, residents of Gopalpura village in the Moth area. They had gone to Chirgaon for work. Police said the truck hit the motorcycle with great force, killing both victims on the spot and dragging them for nearly 100 metres. The impact was so severe that Sumit Kumar's head was severed from his body....
