Four Bangladesh nationals were among those killed in Thursday's suicide bomb attack on a Saudi mosque, diplomatic sources in Dhaka confirmed yesterday.

Four more Bangladeshis were injured in the attack, the sources said, adding that the Bangladesh foreign ministry was likely to provide details about the victims' identities today.

An Islamic State group suicide bomber detonated an explosives-packed vest in a mosque inside a Saudi Special Forces headquarters, killing 15 people on Thursday. In the latest string of ISIS attacks in the kingdom, the bomber struck during noon prayers in the city of Abha, in the southern province of Asir near the border with war-strewn Yemen, the interior ministry said.

A ministry spokesman, quoted by al-Ekhbariya state television, said 11 of those killed were policemen and four were Bangladeshis who worked at the police compound, reports Al Jazeera.

One Bangladeshi victim was identified as Jibon, son of late Belal, of Asadnagar village in Brahamanpara upazila of Comilla, reports UNB.

Earlier yesterday, Prime Minister Sheikh Hasina condemned the attack and expressed her solidarity with the Kingdom to fight against terrorism in any form.
