A series of car bombs at mosques and the headquarters the Houthi group in the Yemeni capital Sanaa has left several people dead on the eve of Ramadan.

At least 23 people have been killed and dozens more injured following the explosions at three mosques and the homes of Houthi rebel leaders, reported AFP. Officials said the attacks took place in the northern and central parts of the capital.

"Four car bombs targeted the political bureau of Ansarullah, the Hashush mosque in the Jiraf district, the Kibsi mosque in the Zira district, and the Qubat al-Khadra mosque, causing the martyrdom and injury of dozens," an unnamed security official told Reuters on the basis of anonymity.

Earlier in the day, Houthi fighters attacked the home of politician Abdel-Aziz Jubari in central Yemen while he was attending UN talks in Geneva.

Both attacks took place while the UN was pushing for a truce during the Ramadan period, talks of which Yemen's Foreign Minister Reyad Yassin Abdulla said were "going nowhere".

Since March, more than 1,400 civilians have been killed as Saudi-led air strikes targeting the rebels who overran the government of President Abed Rabbo Mansour Hadi.
