"Because of them, probably the world is going to change and those refugee like me, myself, they will have hope." the boy's father told his sisterFriday, taking solace in the symbol his child has become.

Alan Kurdidrowned and was found washed ashore after theboat he was in, loaded with refugees fleeing the bloody Syrian war, capsized on the way to Greece.

Alan, 3, his brother Ghalib, 5 and the boy's mother Rehanna, drowned.

"Those kids, those angels, break everybody's heart ... all this government people like us, they have kids, they have family ... and I'm sure this is something they don't like to happen anymore to anybody," TimaKurdi, the boy's aunt said on Friday.

The surviving father, Abdullah Kurdi, was flown to Syria by the Turkish government to bury his family on Friday.

For that, his sisterwas grateful.

"[Abdullah]said they put them in a beautiful coffin."

Tima, wholivesCoquitlam B.C., described her brother's need to be near his boys for the funeral.

"His place is going to be beside the coffin. He said he just wantto feed them, give them some water if they arethirsty, give them some food that's what he want to do until he die."

Shattered by the loss, the family istaking some solace in the news that four men now face chargesin connection withthe capsized boat that led to the drownings.

Today she braces herself for another emotional wringing,a memorial set for 2 p.m. PT at Simon Fraser University's Harbour Centre in Vancouver, which is attracting worldwide attention.

'Need the world to step in'

"We need the world to step in," said Tima Kurdi.

She says the family was fleeing Kobani, a town inSyria,after Islamic State militants beheaded her sister-in-laws' relatives. Kurdi described the trip as the "only option" left for the family to have a better life in Germany or Sweden.

Another brother had applied to Canada for refugee status, but was declined,said Kurdi, who appealed to Canada to fix the process that hinders many refugees.

"I respectfully implore our government to work immediately to improve the application procedure based on the current humanitarian crisis ... these issues that have existed long before my family's tragic loss this week." she said on Facebook.

Four Syrians were arrested Friday in the case.

Prosecutors claim the men took money to try to smuggle refugees to the Greek island of Kos.

They're accused of "conscious negligence" in connection with 12 drownings of people who were on the same boat.
