Iraq sent armoured vehicles on Monday to reinforce its long border with Syria, in a bid to ease concerns after a surprise offensive in the neighbouring country by Islamist-led insurgents.
The lightning offensive by Islamist Hayat Tahrir al-Sham (HTS) group and allied factions saw government forces lose full control of Syria's second city Aleppo for the first time since the civil war began in 2011.
The attacks have caused unease in Iraq, which still bears the scars of decades of conflict, including the rise of jihadists from the Islamic State (IS) group.
