The agency has pulled out all four staff working in Baghdad, where it set up following Saddam Hussein’s toppling in 2003, and suspended the October opening of its new office in northern Iraq’s Erbil region.
It has also withdrawn four staff from its office in Tripoli, Libya, which it set up in the wake of the overthrow of Colonel Gaddafi three years ago, while two volunteers remain.
Both countries are in the grip of violence, with Islamic State seizing swathes of Iraq, while militias have taken control of Tripoli.
It is understood that staff will relocate elsewhere within the agency’s Middle Eastern network.
Tony Christodoulou, CEO of Action Global Communications, said: "When I set up Action more than 40 years ago as an agency introducing quality PR services to emerging markets, it became apparent to me very quickly how important it is to have flexibility not only in the services we offer our clients, but also in our own operations.
"I strongly believe that both Libya and Iraq will come back from their respective situations stronger than ever in the future. Both countries have a huge amount of potential that I have already seen first-hand, but the safety of our employees means that we had to find a flexible solution for them to continue to work in a safer environment."
