Calm is returning to the streets of Tunisia's capital, even as pressure is growing on the governing Islamists to find a solution to the country's biggest crisis since it set off the Arab Spring uprisings two years ago.

The killing of a Tunisian opposition leader last week brought protests against a government accused of pandering to extremists. The prime minister wants to appoint a new government of technocrats to ease tensions.

But his Ennahda party rejects the idea. Ennahda's governing committee is meeting Sunday to discuss it, amid signs of a growing split between party moderates and hard-liners.

After three days of street violence, the streets in the capital Tunis are relatively quiet Sunday, under the watchful eye of riot police.
