Yemen's Houthi rebels said that they fired a rocket towards a government military training camp in neighboring province of Marib on Sunday evening, the Houthi-run al-Masirah TV reported.

"The rocket targeted the operation room in Tadawin camp in northern Marib, killing at least eight soldiers and injuring seven others," the television quoted a statement from the group's military spokesman Yahya Sarea as saying.

There was no confirmation yet from the government, which controls the country's oil-rich Marib, about 173 km east of the Houthi-held capital Sanaa.

Yemen has been mired in civil war since late 2014, when the Iran-backed Houthi militia seized control of several northern provinces and forced the internationally-recognized government of President Abd-Rabbu Mansour Hadi out of Sanaa.

The war has killed tens of thousands of people, displaced nearly 4 million and pushed the country to the brink of famine.
