SICK ISIS supporters have celebrated the depraved suicide bombings in Sri Lanka by posting a blood-splattered poster featuring Pope Francis and Donald Trump.

The Easter Sunday massacre left at least 359 dead and is believed to the terror group’s biggest ever mass murder.

After claiming responsibility for the atrocity, the brainwashed death cult’s official media channel Amaq issued a disturbing poster.

The chilling propaganda post featured the masked extremists believed to have carried out the bombings in Sri Lanka above images of the Pope, US President Trump and a statue of Buddha.

Along with splatters of blood, the sinister image also includes depictions of fire.

On the poster, the warped militants wrote: “We will not make you cry of blood, enemies of religion and the first of the clouds shall fall upon the rivers of unclean blood.”

The coordinated attack, which involved nine suicide bombers, is believed to the terror group’s biggest ever mass murder.

ISIS’s previous largest attack was a bomb assault on a shopping district in Karrada, Baghdad, which left 340 dead in 2016.

Their deadliest attack in Europe remains the Paris massacre in November, 2015, which claimed the lives of 130 innocent people.

WHAT WE KNOW SO FAR:

At least 359 people killed and 500 injured after nine suicide bombers attacked three churches, four hotels and a block of flats in Sri Lanka

Thirty-nine foreigners were killed including eight Brits, 'several' Americans, one Dutch, one Chinese, two Turkish, three Danes and one Portuguese national

40 suspects have been arrested

Authorities name local Islamic terror group National Thowheeth Jama'ath as being responsible for the attacks saying they were helped by 'international network' of jihadis

ISIS claims the suicide bombers were 'soldiers of the Islamic State'

Meanwhile, one of the suicide bombers who studied in the UK has been identified as Abdul Lathief Jameel Mohamed.

He is believed to have attended a university in the southeast of England between 2006 and 2007, security sources told Sky News.

He was responsible for the smaller suicide blast at the Dehiwala hotel in southern Colombo hours after the later explosions, it has been reported.

Officials earlier revealed that the twisted ISIS extremist also studied for a post-graduate degree in Australia.

It has since emerged that he attended a university in Melbourne, reports the Age.com.

Speaking at a news conference, State Minister of Defence Ruwan Wijewardene said: "We believe that one of the suicide bombers studied in the UK and later did his postgraduate studies in Australia before coming back to settle in Sri Lanka."

The bombshell revelation that one of the depraved extremists studied in the UK has sparked fears that he could have been radicalised while living in this country.

Authorities said that there were nine suicide bombers, including a woman, who murdered at least 359 people on Easter Sunday.

Speaking about the extremists' backgrouds, Mr Wijewardene said: “Some of the suicide bombers – most of them are well educated and come from maybe middle and upper middle class.

“So they are financially quite independent. Their families are quite stable financially. So that is a worrying factor in this.

“They studied in various other countries. They hold degrees. They are quite well educated people.”

In 2016, the Sri Lankan government said that 32 of its Muslim citizens from “well-educated and elite” families had fled to Syria and joined ISIS although it's not clear if any of those fighters were involved in Sunday’s attack.

And in an astonishing revelation, Mr Wijewardene said that top intelligence officials deliberately hid information on the attacks and security chiefs did not take action.

The minister also said the massacre must have been planned for at least seven or eight years.
