Syrian civil war could engulf Middle East, UN envoy says Syria's civil war could engulf the whole of the Middle East, the UN-Arab League envoy Lakhdar Brahimi said on Wednesday. The former UN diplomat made his comments during a visit to Beiruit amid ongoing exchanges of artillery fire between Turkish and Syrian troops at the border between the two nations. Brahimi said that Syria's neighbours "should realise...that this crisis cannot remain inside Syrian borders indefinitely. Either it will be addressed or it will overflow. The successor of former peace envoy Kofi Annan added that he was visiting countries neighbouring Syria in order to gain an insight into their views on the Syrian conflict. Lebanon is Brahimi's latest stop in his second tour of the Middle East region. Although Brahimi confirmed that he would visit Damascus, he did not mention a specific date. Unconfirmed media reports indicated that the envoy would touch down in Syria on Thursday. Meanwhile, a Syrian mortar bomb landed inside Turkish territory on Wednesday, according to the Anatolia news agency. There were no casualties. Border troops in the Hatay province immediately fired off a mortar strike at Syria in retaliation. More about: Arab League, Armed conflicts, Bashar al-Assad, Syria, Turkey, United Nations
