Rebels in the Syrian city of Aleppo have set off a massive suicide lorry bomb to seize back a strategic ruined hospital occupied by Assad loyalists.
A huge fireball engulfed the al-Kindi Hospital, the blast bringing down the central section of the disused building, in Friday's daylight attack.
Militants driving up in an armoured personnel carrier later piled into one of its wings.
According to an unconfirmed report, 35 rebels died in the attack.
The hospital stands close to a besieged government prison.
Analysts say the capture of the ruined hospital does not alter significantly the balance of forces in Aleppo, Syria's battle-scarred second city, but it is a boost for the rebels and their Islamist allies after recent reverses.
