Turkey's foreign ministry has summoned the senior Egyptian diplomat in the country to protest against a raid by Egyptian police on the Cairo office of Turkey's state news agency, Anadolu.

Four employees of the agency, one Turk and three Egyptians, were arrested following a police search on Tuesday night.

Turkey condemned what it called the act of harassment and intimidation against the Turkish press, and called for the immediate release of those arrested.

Relations between the two countries have been strained since the 2013 military coup in Egypt ousted President Mohammed Morsi, whose Muslim Brotherhood administration was supported by Turkey.
