Dozens have been killed in a hospital in Syria's Aleppo after rebel forces reportedly launched an attack on Tuesday. It had been reported earlier that seven people had died on Tuesday in Syrian Army and rebel firing in the region. Fighting between government forces and the Jaish al-Islam restarted in the region overnight after a brief truce, Reuters reported.

At least six civilians died and 37 were injured on Tuesday after rocket shells were fired on government-held areas in Aleppo, a source at the Aleppo Police Command told the Syrian news agency SANA. Civilian houses on al-Neel Street, al-Siryian, al-Khalidyia, al-Moukambou, al-Sabil reportedly suffered massive damage because of the attacks.

A source at the Aleppo Health Directorate told SANA that the injured were mostly children and women, and that they had suffered critical injuries. The toll could increase, they said.

However, Associated Press reported on Tuesday at least nine people died and many others were injured as government and rebel forces attacked each other. At least two people were killed in rebel-held areas and seven in government-held areas after attacks in the morning.

The Syrian Observatory for Human Rights (SOHR) said there was a child among the seven dead. The U.K.-based human rights group said 250 people have died in the last 12 days in Syria.

In Raqqa, believed to the Islamic State group's capital, airstrikes were conducted. It is however not known which group — the U.S. or Russia — led the attacks.
