Britain has called on Russia to respect its commitment to international human rights after detaining over 1,000 people in Moscow and other Russian cities on Saturday in protests against the detention of opposition leader Alexei Navalny, Reuters reported.

"We are deeply concerned by the detention of peaceful protesters and continue to monitor the situation closely," the British foreign ministry said in a statement.

"We urge the Russian government to respect and comply with its international commitments on human rights, and release citizens detained during peaceful demonstrations."
