Family and friends gathered at the Ottawa Mosque Saturday to remember 23-year-old Nusrat Jahan.

Dozens packed the mosque for a traditional funeral followed by a private reception and burial.

Abdullah Al Nasser, Jahan's brother, said his sister's death has rocked their family.

"Our world was turned upside down in one day," he said. "We've lost everything."

Jahan and her family moved to Ottawa from Bangladesh three years ago. Her father works at that country's high commission in Ottawa. Al Nasser said Jahan was the youngest child, and the family's only daughter.

"She was the one who took care of us. She was the smallest, but always the one who took care of everyone," Al Nasser said.

The President of Willis College said Jahan had just started the school's business administrative program and wanted to become an accountant. Fellow students said they will remember Jahan as a bright, talented individual who always had time for others.

"She was a genius. She was very smart, very intelligent," said Jahan's desk mate, Emmenuel Ngyia."She was really, really a good person and I really miss that about her."

Jahan was cycling to class at Willis College in the Laurier Avenue bike lane when she was hit and killed by a truck. Witnesses said the truck was making a right hand turn off Laurier onto Lyon when the crash happened. The tragedy has put the spotlight on cycling safety in the capital, with some councillors calling for changes to this city's infrastructure.

Jahan's family and friends said they hope the city can make changes to make the roads safer.

"We want justice. We want this thing investigated and proper punishment paid," said Rasheda Nawaz, a close family friend. "It's so difficult."

Jashim Ahmed witnessed the fatal collision early Thursday morning and said he hopes the city will act.

"They could do something to save our citizens and our people and everybody, to make sure it doesn't happen anymore."

Ottawa Police are still investigating and are asking anyone with information about what happened to come forward.
