Gunmen from the Shia militant group Hezbollah have seized most of western Beirut, driving out supporters of the Western-backed government. The gunmen, who also back Hezbollah’s Shia opposition allies, have forced the closure of pro-government media. The fighting was sparked by a government move on Monday to shut down Hezbollah’s telecoms network. At least 11 people, mainly civilians, have been killed and dozens injured in the city in three days of clashes. The UN Security Council has urged the rival parties to stop fighting amid fears of civil war breaking out.
