Demonstrators blocked several roads in and around Beirut with burning tyres on Wednesday as part of an anti-government protest backed by Lebanon's Hezbollah-led opposition, witnesses said.
The main road leading to the capital's international airport was among routes blocked by the protesters.
Security forces were deployed ahead of a march called by union leaders for later on Wednesday.
On Tuesday, the Western-backed government accused Hezbollah, a political group with an army, of violating Lebanon's sovereignty by operating its own communications network and installing cameras at Beirut airport.
The government, supported by the United States and a number of Arab countries including Saudi Arabia, also removed the head of Beirut airport security.
Hezbollah said the communications network was part of its security apparatus and had played a major role in its war with Israel in 2006.
