SANAA, Yemen, March 16 (UPI) -- Houthi rebels operating in north Yemen are violating the terms of a cease-fire reached in February, Yemeni security agencies said Tuesday.
Yemen launched a scorched-earth campaign against Houthi rebels in August, breathing life into a conflict that has simmered since 2004.
Saudi Arabia entered the fight in 2009 when Houthi rebels stormed border checkpoints.
A cease-fire reached in February appeared to hold while Yemeni authorities tackled a violent separatist uprising in the south.
A Yemeni security committee said Tuesday, however, that Houthi rebels were "putting obstacles" up against authorities monitoring the truce, the official Saba news agency reports.
"The Houthis are refusing to deliver land mines, which have been removed in some areas, to the government in order to be destroyed," the committee said.
The committee added that Houthi rebels set up new checkpoints and launched attacks on "some public and private installations" in the northern provinces.
Security officials called on Houthi rebels to recommit to the cease-fire and make way for displaced persons to return to their homes.
Relief groups in the wake of the August offensive complained the fighting was creating a humanitarian crisis in Yemen.
