In 2012, the Syrian civil war threatened to spill over in Lebanon, causing more incidents of sectarian violence and armed clashes between Sunnis and Alawites in Tripoli. According to UNHCR, the number of Syrian refugees in Lebanon increased from around 250,000 in early 2013 to 1,000,000 in late 2014. In 2013, The Lebanese Forces Party, the Kataeb Party and the Free Patriotic Movement voiced concerns that the country's sectarian based political system is being undermined by the influx of Syrian refugees. On 6 May 2015, UNHCR suspended registration of Syrian refugees at the request of the Lebanese government. In February 2016, the Lebanese government signed the Lebanon Compact, granting a minimum of €400 million of support for refugees and vulnerable Lebanese citizens. As of October 2016, the government estimates that the country hosts 1.5 million Syrians.
