Worshippers believe the Virgin Mary appeared in the clouds above a shrine right on cue yesterday after a teenage boy was told to expect a vision of Our Lady.
Crowds of people gathered at Knock Shrine in County Mayo, Ireland, at 3pm on Saturday, expecting to see a vision of the Virgin Mary.

They headed to the shrine after a Portuguese traveller boy, 14, told his family how our Blessed Lady and others appeared to him in a vision during a visit to Fatima in May.
Millions of people believe the Virgin Mary appeared at Knock in 1879.
Yesterday, thousands waited once again, hoping to catch a glimpse of her.
Initially, it seemed she had failed to appear - but now a video has emerged on social media showing what worshippers claim is the Virgin Mary in the clouds above the shrine.
The video was posted on Facebook by Biddy Connors, who wrote: "Our lady appeared in knock today. Astonishing Never get over what i seen. Please watch."
It's not clear where exactly the image of the Virgin Mary is in the clouds pictured.
The Portuguese boy was reportedly told by the Virgin Mary that she would appear at Knock and bless those present.
Subsequently, news of his claims spread through the traveller community via social media.
The boy's father posted an audio message online describing what his son had witnessed at the shrine in Portugal.
He said: "For two days our son seen Our Lady in Fatima and he seen the visionaries.
"The visionary from Medjugorje was speaking to him in Portuguese and (he) was able to understand every word out of her mouth."
He added: "On the tenth of June we will be going to Knock and whoever wants to come is welcome. Our Lady will appear...
"Whoever wants to be there at three o'clock Our Lady will come down, I can't say if the three visionaries will be there, but I know Our Lady will be there.
"It's out there for everybody who believes in it."
He admitted he felt "stressed" and what had happened was a lot for his young son to take in.
