A suicide bomber and car bomb detonated outside of the Iranian embassy in Lebanon's capital, Beirut, on 19 November. The blast in the Bir Hassan district left at least 23 people dead and 146 more wounded. Among the fatalities were members of the Iranian diplomatic representation. It is unclear at this time which group coordinated the attack; however, given the location and target of the attack a connection to the Syrian conflict is likely. Sunni rebels and militant groups battling the Syrian regime have threatened to carry out retaliatory attacks against the Syrian government's allies, specifically Hezbollah, which maintains a strong presence in southern Beirut, and Iran, on a number of occasions since the start of the Syrian civil war in 2011. There is evidence to suggest that the spate of recent bombings in Beirut and the wider country are directly connected to the conflict in Syria (see below). The ongoing fighting in Syria will continue to stoke tensions and further retaliatory action is likely in Lebanon.
