Today, the world's largest conjoined twin Ronnie and Donnie, has passed away at the age of 68.

Jim, the conjoined twin brother, announced that Ronnie and Donnie had died this morning in Dayton, Ohio, USA.

According to American media, the twins have lived with Jim and his wife Mary in Beverkrick for 10 years in order to take care of them.

In 2010, 200 volunteers from the area helped expand Jim's home so that the twins could live comfortably, after they felt arthritis, and staying in their former home in Dayton became unsafe for them.

The late conjoined twins became the longest-lived conjoined twins in 2014.
