Aleppo, the scene of the harshest battles of Syria war, had received 67 percent of all returnees.

:: More than 600,000 displaced Syrians have returned to their homes since the beginning of the year, with most of them heading to Aleppo, according to figures from the International Organization for Migration.

Between January and the end of July, 602,759 displaced Syrians returned to their homes, many of them citing an improved economic and security situation in the areas they had fled from, IOM said in a statement.

A total of 84 percent of those who have returned had taken refuge elsewhere within the war-ravaged country, while the remaining 16 percent returned from neighboring countries Turkey, Lebanon, Jordan and Iraq.

More than a quarter of returnees said they did so to protect their assets and properties, while nearly the same number referred to the improved economic situation in their place of origin, and 11 percent cited the improved security situation there.

Fourteen percent meanwhile pointed to the worsening economic situation in their place of refuge, IOM said.
