Abu Dhabi (CNN) The Middle East and North Africa is witnessing a surge in Covid-19 cases aggravated by the Delta variant of the virus -- and it may get worse over coming weeks -- according to the World Health Organization (WHO). Across the region, more than 11 million cases have been recorded in total since the start of the pandemic. Tunisia, one of the Arab world's worst-hit countries by the Delta variant, has reimposed lockdowns. It has also appealed to Arab Gulf countries for critical aid, as its health care sector faces "catastrophe," according to the Tunisian government. Saudi Arabia has announced that it will send Tunisia 1 million vaccine doses, and the UAE has also donated half a million vaccines.
