In brief
The UK has closed its embassy in Cairo after security barriers outside were removed, which was prompted by rising tensions following the arrest of a pro-Egyptian activist in London. The situation is under review as the embassy remains operational but its main building is closed for the time being.
The British embassy in Cairo has been closed temporarily after security barriers were removed from outside the building.
Barriers in the city's Garden City district were removed by the Egyptian authorities on Sunday, the Foreign Office said in a statement.
The embassy remains operational but the main embassy building will be closed while the impact of these changes is reviewed, it added.
The decision follows growing calls in the country for a retaliatory response to the UK's handling of protests outside Egypt's embassy in London, reports say.
Last week a prominent pro-Egyptian government activist was arrested in London, and later released, after apparently confronting protesters outside Egypt's embassy, Daily News Egypt reported.
Egyptian Foreign Minister Badr Abdelatty reportedly called British National Security Adviser Jonathan Powell last week to ask for an explanation for the arrest.
Abdelatty has previously said Egypt has the right to respond and reciprocity against countries that failed to provide protection for Egyptian embassies in accordance with the Vienna Convention.
The arrest also sparked a row in Egypt, with some political figures urging Egyptian authorities to remove barriers from Britain's embassy in Cairo.
BBC News understands the UK government is continuing to engage with Egyptian counterparts over the security of the embassy in Cairo and the safety of staff.
The Foreign Office has provided phone numbers on the Egypt travel advice tab of its website for those in need of consular assistance. The page does not advise against travel to Cairo, but does advise against travel to certain parts of Egypt.
Large barriers have been installed around the UK and US embassies in Cairo for decades, which critics in Egypt say have disrupted traffic on streets in the area.
The British embassy in Cairo previously closed temporarily in 2013 and 2014 in relation to separate security concerns.
