Syrian troops and rebels continue to clash in the northern city of Aleppo, with each side claiming victory.

The government said it had overrun the district of Salahhedine and inflicted great losses against the rebels.

However, rebel forces rejected the report and said that although fighting was ongoing, no government forces were in the neighborhood, a rebel stronghold.

Syrian Foreign Minister Walid al-Moallem vowed the rebels in Aleppo will be defeated. He made the comment on a visit to Iran, Syria's strongest regional ally.

At a joint news conference with Moallem, Iranian Foreign Minister Ali Akbar Salehi dismissed any hopes of a peaceful transition in a post-Assad Syria, calling them an “illusion.”

U.N. humanitarian chief Valerie Amos said in a statement Sunday that the fighting has forced 200,000 people to flee the area over the past two days.

She said the fighting is making it hard for humanitarian agencies to provide displaced residents with urgently needed food, mattresses, blankets, hygiene supplies and drinking water.

Also Sunday, Jordan opened its first official tent camp for refugees from neighboring Syria. Foreign Minister Nasser Judah said Jordan has taken in 142,000 Syrians, with up to 2,000 more arriving each day.

Turkey has been sheltering more than 44,000 Syrians.
