On 12 November 2015, two suicide bombers attacked Bourj el-Barajneh, a southern suburb of Beirut, Lebanon, that is inhabited mostly by Shia Muslims.

They were arrested in a Palestinian refugee camp located in Burj al-Barajneh and a flat in the capital's eastern district of Achrafieh, which had allegedly been used to prepare the explosive belts.

The initial plan was apparently to send five suicide bombers to a hospital in the neighbourhood, but heavy security forced them to change the target to a densely populated area.

"[citation needed] Secretary-General of the United Nations Ban Ki-moon called on Lebanon to "not allow this despicable act to destroy the relative calm that has prevailed in the country over the past year.
