Maldivian troops blockaded Parliament and clashed with Opposition leaders for a second day, witnesses said on Tuesday.

The latest turbulence came as the U.K. urged its citizens to take caution in the capital Malé after soldiers tear gassed protesting politicians there.

Soldiers barred the main opposition Maldivian Democratic Party (MDP) from entering the heavily guarded Parliament complex again on Tuesday, with witnesses reporting shoving as MPs were forced back from the barricade.

“Even when Parliament is not in session, MPs are free to go to the building and attend to their work, but it is not allowed now,” MDP spokesman Hamid Abdul Ghafoor told AFP. “This is ridiculous.”
