South Korea's parliament passed a revised bill to prescreen airline passengers to keep potential terrorists from flying into the country, the government said Thursday.

The National Assembly, led by the ruling Saenuri Party, endorsed the revision to the immigration control law Wednesday, which calls for the checking of passenger manifests before airlines issue boarding passes, the Ministry of Justice said in a press release.

South Korea has been running a test operation of the prescreening system in several airports, including Nagoya Airport in Japan, since February 2015.

During the period, the ministry said it banned more than 350 people, including sex and drug offenders, from boarding flights bound for South Korea by checking over a million passengers in advance.

In recent months, Incheon International Airport, South Korea's main gateway, has been hit hard by a series of security breaches.
