At least 13 people have been killed in Saudi military attacks�on a bus carrying the employees of a private company in Yemen�s southwestern Ta�izz Province.

The bus was hit on the road linking the city of Ta�izz with the capital, Sana�a, on Thursday. Fourteen people were also wounded in the attack.

Saudi fighter jets have also targeted a mosque and a house in the Saqayn district of the northwestern province of Sa�ada.

Warplanes also carried out three airstrikes on Kitaf district of the same province.

Earlier in the day, Riyadh launched a series of airstrikes on the Sirwah district of Ma�rib Province.

The attacks come two days after Saudi Arabia bombarded a hospital in the Heedan district of Sa�ada, run by medical charity group Doctors Without Borders (MSF).

Yemen has been under Saudi airstrikes on a daily basis since March 26 when Riyadh launched a ferocious military campaign against the impoverished nation.

The kingdom is apparently trying to undermine the Ansarullah movement, and return fugitive former Yemeni President Abd Rabbuh Mansour Hadi�to power.

About 7,000 people have lost their lives in the Saudi attacks while nearly 14,000 others have been injured.

Retaliatory attacks

Meanwhile in a retaliatory attack, Yemeni forces shot down a Saudi logistic helicopter in the Jabal Sabir district of Ta�izz on Wednesday.

The helicopter was reportedly airdropping arms and munitions to terrorists and Saudi forces.

Yemeni fighters also launched several Grad rockets at Saudi military bases in the country's southwestern border regions of Jizan and Najran.
