Sri Lankan officials say the terrorist attack that killed 290 people, including two Australians, was carried out with the support of an international network.

The country’s government is blaming a little-known local jihadist group for the attack.

The two Australians killed have been identified as mother Manik Suriaaratchi and her daughter Alexendria, 10, pictured above.

I can also confirm two other Australian citizens were injured in the attacks. They have received medical treatment for their injuries and are recovering. My thoughts and prayers are with the family and friends of those who have passed away and the injured.

Two Australian women – one in her mid 50s, the other in her 20s – have also been injured.

One is being treated for shrapnel wounds, while the other has a broken leg. Both are in stable conditions.

24 people have been arrested in a series of raids.

Meantime, there’s a growing row over an apparent failure in communication in the lead-up to Sunday’s devastating attacks.

Churches and luxury hotels were targeted by suicide bombers in the Easter Sunday terror attacks with another explosive device found near Colombo International Airport.

Australian man Sam, 27, was having breakfast with a friend at the Shangri-La Hotel in Colombo when two bombs went off.

“A lot of people around us were covered in blood – we both had blood on us,” he told Macquarie National News.

Sam wasn’t hurt, thankfully, telling 3AW he was about “5 to 10 metres away” from the initial blast.

Australia’s political leaders condemned attacks, with Prime Minister Scott Morrison being briefed on the situation.

Opposition leader Bill Shorten said his thoughts were with Australia’s Sri Lankan community who would be in shock at the extent of the attacks.

At least 35 foreign nationals have been killed.
