A Belfast-made missile launcher has reportedly been spotted in a video downing a Russian drone in Ukraine.
The missile is launched from the ground by a soldier using a system which Ukrainian soldier Yuri Kochevenko has identified as the Starstreak.
The soldier then cheers after reportedly striking the Russian drone and destroying it.

But the roots of the equipment used to strike a blow against the Russian army can be traced back to Belfast.
The missile launcher is made and designed by Thales UK at their Belfast site, along with another short range missile system called the LMM.
It also helps to assemble the Saab NLAW missile launcher in its final stages.
The Ministry of Defence purchases the missile systems from Thales and it is understood those sent to aid Ukrainian forces have been taken from existing purchased stock.
The Starstreak fires missiles using laser beam riding guidance technology and fire at speeds of up to Mach 3.
Thales claims on its website that it can be used in surface situations or for launching surface-to-air attacks against helicopters and other aircraft.
A workforce of 650 are involved in the high-end engineering work at the Thales Belfast factory, which an industry source described as essentially "rocket science".
It is understood the site is the only location in the UK where both the Starstreak and LMM systems are 100% designed and manufactured.
A source told Belfast Live that the capacity exists at the plant to produce the missile systems from scratch should the MoD need to produce more for its own defences or to help Ukraine.
The majority of engineers are involved in defence projects, but it is not the only work undertaken by Thales in Belfast.
Staff also work on creating electric propulsion systems for satellites, involving elite level engineering work.
An industry source has described the Belfast plant as a key site for its UK work.
Thales took over the former Shorts Missile Systems site in 2001 and has previously said it contributes £35million to Northern Ireland's GDP.
