Members of the infamous anti-gay Westboro Baptist Church have threatened to picket the site of the Sandy Hook Elementary School shooting less than a day after the tragedy, claiming that the shooting was God’s punishment for the state of Connecticut legalizing same-sex marriage.

Prominent church member Shirley Phelps-Roger made the threat via twitter, posting ‘Westboro will picket Sandy Hook Elementary School to sing praise to God for the glory of his work in executing his judgment.’

Another church member tweeted, ‘God Almighty smacked USA with #Sandy & she's brazen in her sin still; THEN He gives you a right hook - make that #SandyHook! #RepentingYet??

Westboro pastor Fred Phelps tweeted in relation to the shooting, ‘That’s the message that this evil nation and world need: that God Almighty is on the march & nothing is gonna stop Him.’

Westboro Baptist Church members threatened to protest before and after an interfaith memorial service for the victims of the shooting on Sunday in Newtown, Connecticut which will be attended by US President Barack Obama.

The Westboro Baptist Church styles itself as ‘the most controversial church in the world’ and is also known for its anti-semitic and islamophobic rhetoric.

Members of the Reddit.com website have pledged to form a silent blockade to prevent the Westboro Baptists from reaching the school.

The following day the Westboro Baptists plan to picket the funeral service of a two year old girl who was killed by a dog in their home town of Topeka, Kansas.

‘This little child is paying for the sins of Topeka, of Kansas, and – like those children killed in the Connecticut elementary school last Friday – of the United States,’ the church said in a statement.

‘One of the things God does to a people who adopt policies of disobedience is bereave them of their children.’

The news comes a day after American Family Association spokesman Bryan Fisher blamed the shooting on ‘liberals’ taking Christian prayer out of schools.

‘Back when we had prayer, the Bible and the Ten Commandments in schools, we did not need guns,’ Fisher said.

Twenty children and six adults were murdered in the mass shooting with many victims shot multiple times in what is believed to be the second worst mass shooting in US history.

The suspected shooter, Adam Lanza, 20, had already murdered his mother before attacking the school and later turned the gun on himself.
