The Muslim holiday of Eid al-Adha was observed by Syrian President Bashar al-Assad on Saturday in Aleppo, his first trip to the northern city since his forces retook it in 2016 with assistance from Russia and other allies.

SANA, the state news agency of Syria, said that Assad and other senior government figures attended the Eid al-Adha prayers at the Ibn Abbas mosque.

In his remarks, Assad said he visited historic marketplaces and inaugurated a thermal power plant that is expected to generate 200 megawatts of electricity, according to SANA.

The city produced 1,000 megawatts of power before the fighting erupted there in 2012, one year into the uprising against Assad.

His forces recaptured the city in late 2016 with help from Russian warplanes and Iran-backed armed groups. Tehran then signed a deal to rehabilitate five power plants in Aleppo.

Much of the city’s infrastructure had been left in ruins by the fighting, which also ravaged the Old City – a UNESCO World Heritage site.
