Two blasts in the central Syrian city of Homs have killed at least 32 people and wounded dozens.

The Homs blasts came amid reports that Syrian government forces captured 31 villages in the northern province of Aleppo from the extremist Islamic State group.

Syrian troops have been on the offensive in different parts of the country under the cover of Russian airstrikes.

The television report said Sunday's blasts struck in the pro-government neighbourhood of Zahraa - a frequent target for similar explosions.

The report quoted Homs governor Talal Barrazi as saying that 32 people were killed and dozens others wounded, some seriously.

Most of the bombing attacks in Homs over the past months have been claimed by IS, which controls parts of Homs province including the historic town of Palmyra.

The Britain-based Syrian Observatory for Human Rights, which relies on a network of activists around Syria, said the blasts killed 46 and wounded more than 100.

The Observatory said the blasts were caused by two vehicles rigged with explosives.

State TV said the blasts occurred on Sunday morning saying they were the result of two car bombs.

The report aired footage of the destruction caused by the blasts.

Debris and mangled cars filled the streets and the charred body of a man was seen being taken away on a stretcher.

The Zahra neighbourhood is predominantly Alawite, the minority Muslim sect to which President Bashar Assad belongs.
