4 US F-22 stealth fighter jets patrol over South Korea amid growing tensions with North

Four US F-22 stealth fighters are flying over South Korea amid growing tensions following North Korea's rocket launch.

The high-tech planes capable of sneaking past radar undetected were seen flying near a US air base near Seoul on Wednesday.

Pyongyang will likely view the arrivals of the planes as a threat as they are a clear show of force against the country.

The United States often sends powerful and sophisticated warplanes to South Korea in times of tension with North Korea.
