As weather experts predict that this winter will be one of the harshest for Riyadh in years, some residents of a neighbourhood in the capital of Saudi Arabia are helping those in need, reports Arab News.

A video has gone viral on Twitter showing pictures of blankets hanging on trees in Al-Rayyan district for those in need to keep warm.

Sultan Al-Mousa, who tweeted the video, said he hopes it will encourage more such initiatives, the Arab News reported. 

But as the neighbourhood is considered well-off, there has been criticism that the gesture could have had a bigger impact in poverty-stricken areas such as Al-Oud, Al-Bathaa and Manfooha.

"The gesture is noble, but there should've been some thought beforehand."
