At least eight people have been killed after a gunman opened fire on worshippers at a mosque in Yemen, officials have said.
Many others were reported to have been injured in the attack in Amran province, north of the capital, Sanaa.
Following the shooting, the gunman was arrested and taken for questioning, officials said.
Yemen has seen renewed fighting between government forces and Shia rebels in the north of the country.
A number of attacks targeting foreigners in Yemen have been linked to al-Qaeda.
Eighteen people were killed in a bombing at a mosque in the northern city of Saada earlier this month.
