A look inside the ruins after they were recaptured from so-called Islamic State in March
Islamic State group fighters have re-entered Palmyra, nine months after losing the ancient Syrian desert city.
Monitoring groups say militants and pro-government forces fought fiercely in the centre of Palmyra.
An activist there told the BBC that the city was now “more or less” in IS hands.
Reports from Palmyra say about 50 Syrian troops were killed and there was an unconfirmed report that the rest were fleeing.
There are concerns for the safety of civilians still in the city.
The surprise setback for the government of President Bashar al-Assad comes as Russian-backed Syrian government forces are closing in on the remaining rebel-held area of the city of Aleppo.
