Sana'a: A total of 10 teachers were killed and 15 others were injured in different attacks by Al Houthi rebels on dozens of schools in Sa'ada, an official said on Thursday.

Mohammed Al Shamiri, director of education in Sa'ada governorate, said his office received reports that 10 teachers were killed and 15 others injured in addition to unspecified number of students who were killed or injured since the beginning of the war with Al Houthi rebels in August 10, 2009.

The official said that four schools were destroyed and all other schools in the areas under the control of the rebels were turned to barricades.

The schools in the areas under the control of the government or tribesmen loyal to the government were almost all turned into refugee camps for those who have escaped the war, the official added.

Before the war erupted last August, the rebels took control of about 30 schools dismissing all teachers and replacing them with ones believing in Al Houthi ideology. The new teachers replaced the national anthem with the Al Houthi slogan: God is great, death to America, death to Israel, curse to Jews, and victory to Islam.
