Thousands rally amid Yemen crisis
Thousands have been marching for and against Shia Houthi rebels amid a dangerous power vacuum following the resignation of Yemen's leaders, the BBC reported.
President Abdrabbuh Mansour Hadi said he could no longer stay in office as the country was in "total deadlock" after a stand off with the rebels.
Yemen's parliament is to hold a crisis meeting to discuss whether it will accept Mr Hadi's offer.
Meanwhile, aid agency Oxfam says Yemen is nearing a humanitarian catastrophe.
It warned in a new report released on Friday that the country was on "the brink of humanitarian disaster with millions of lives at risk," saying that half of its population was in need of humanitarian aid.
The Houthis, who seized the presidential palace earlier this week, have also encircled the parliament building and the houses of the defence minister and the intelligence chief, the AFP news agency reported.
President Hadi is also under de facto house arrest.
