The beeps on the phone again confirm a failed connection between Aya Natfaji at her home in Sydney's south-west and her parents in Aleppo in north-western Syria.

Aya and her husband, Dr Anas Natfaji, live at Georges Hall with their three children.

The rest of their family is either in Aleppo or have fled to neighbouring Turkey.

Until seven days ago, Aya Natfaji had almost daily contact with her elderly parents and regular contact with her brother and sister's families.

But now no contact can be made on the phone or over the internet and as the United States firms up its position on a possible military strike on Syria, Aya Natfaji is consumed by worry about her family.

"I'm very sad, I'm crying all the time because I've tried maybe thousands of times but no connection, no internet no calls," she said.

Her husband shares her concerns.

"We used to call them almost daily which was really very good and sometimes you call them and you can hear the bombing at the background but at least you know that they are there," he said.

Dr Natfaji believes the Assad government is responsible for the failure to get through on the phone.

"Since the news about the possible strike from the USA, all sorts of communication has been cut off by the regime so we can't contact them at all," he said.

Despite having no contact, Anas and Aya are determined to help their family.

They are flying to Turkey this week with boxes of goods and medicines as well as some gifts that they hope to get into Syria, but they cannot take the risk of going into the war-zone themselves.

While Dr Natfaji left Syria 12 years ago, he still has many friends and contacts and is relying on them to help get the goods over the border and into Aleppo.

"I think in simple ways, I've made some contacts for people who are crossing the borders so we'll try to get these supplies to people who are doing it every day", he said.

While Aleppo may only be a couple of hours' drive from the Turkish border, Aya Natfaji concedes she may not see her family, with it being too dangerous for her to travel into Syria or for them to leave the city.

"I hope to see them when I go to Turkey but I think it's hard, there are snipers on the way and it's very hard so I feel that it's hard to push them to go there" she said.

Dr Natfaji is conscious that it will be difficult.

"We started to feel it even now but I am sure it will be even harder when we get there, it's something beyond imagination, we never thought we would be in a situation like this a few years ago".

Dr Natfaji's own parents have fled into Turkey and he says he is relieved they are no longer in Syria.

"I know that they are at least safe, I'm concerned about their emotions and about their social and mental side of problems they have, talking to my sister, she's possibly going through a bit of depression," he said.

Like most Syrian families in Australia, he also has relations who have been killed in the conflict.

"One of my cousins, she was 48 with four kids, she sent one of them who was 12 to bring some bread from the local bread shop and when he went back, the whole building was collapsed by a rocket, so the whole family got wiped off and he was the only survivor", he said.

As his family prepares to fly to Turkey, Dr Natfaji reflects on the wider political issues and believes western intervention may be the only way to end the bloodshed.

"It's tragic to think that somebody will be bombing your country but how can we stop a dictator from using chemical weapons and continue to kill and kill and kill."
