Zimbabwe's Movement for Democratic Change (MDC) opposition party says at least six people have been killed and scores wounded as tensions increase in the country.
The streets of Zimbabwe's capital city, Harare, are have been deserted following violent protests which erupted on Monday.
Zim's State Security minister announced a security clampdown a day after the country was rocked by protests against sharp fuel hikes.
Sunday Times journalist Ray Ndlovu says the Zimbabwean government has confirmed 200 arrests.
Internet access has been cut off for most of Tuesday, Ndlovu reports, hampering efforts to mobilise and disseminate information.
Ndlovu says he does not foresee an about-turn from President Emmerson Mnangagwa following his announcement to hike fuel prices to over $3 on Saturday.

What has partly caused a lull in activity is the fact that internet services are down since the early hours of this morning. Social media platforms have been shut down. There's not much communication.— Ray Ndlovu, journalist at Sunday Times
