Video footage has been released of the moments before a truck blew up in Pakistan.
Some 53 people were killed in the bombing yesterday outside a hotel in Islamabad.
The images show a lorry stopping at a security barrier and a row between the attacker and the guards.
Sniffer dogs then detect a device and someone shouts to clear the area - then the bomb goes off.
