Several people have been killed or injured in Yemen as Saudi military aircraft conducted a fresh round of attacks against several areas across the impoverished country.

On Thursday, Saudi fighter jets struck the United Nations Children’s Fund (UNICEF) headquarters in the Midi district of Yemen’s northwestern province of Hajjah, located approximately 130 kilometers (80 miles) northwest of the capital, Sana’a, Arabic-language al-Masirah satellite television network reported.

No figure has been reported yet for the casualties.

The development came only hours after five Somali nationals lost their lives and two others sustained injuries when Saudi aircraft bombarded the same region.

Saudi warplanes also fired a number of missiles on residential buildings in the Razeh district of the northwestern Yemeni province of Sa’ada on Thursday, though there was no information on casualties.

Earlier in the day, Saudi forces fired more than 50 mortar rounds at the town of al-Malahit, which is also located in Sa’ada Province.

Additionally, a number of houses were leveled as Saudi warplanes launched ten airstrikes against the al-Marwi Village in the same province.

Saudi Arabia’s air campaign against Yemen started on March 26 - without a UN mandate - in a bid to restore power to fugitive former President Abd Rabbuh Mansour Hadi, who is a staunch ally of Riyadh.

The United Nations says, since March 19, over 1,800 people have been killed and 7,330 injured due to the conflict in Yemen, which was exacerbated by the Saudi airstrikes.
