An elderly Malayali woman was allegedly killed by her daughter-in-law in the UAE-Saudi Arabia border town of Ghayathi Monday night.

The Abu Dhabi police have arrested Shajna (23), a native of Ponkunnam in Kottayam on the charge of murder of her mother-in-law, Ruby Muhammad (63), who hails from Eloor in Ernakulam district.

Ruby's son Sanju, who works in the Al Ansari Exchange in Ghayathi, had recently married Shajna.

It is understood that the two women had issues between them. On Monday, during a fight, Shajna pushed Ruby, who slammed her head against a wall and died, said Sanju.

The body has been transferred to a mortuary and will be brought to Kerala for funeral, Sanju said.

Both Ruby and Shajna had reached Ghayathi on February 15 on visiting visas, which was when Sanju first saw his wife. Their wedding rituals were held virtually.
