The Islamist Huthi movement claims to have also sent drones against Tel Aviv and a ship in the Arabian Sea. In a statement, it says that Israel's aggression will only increase "the great Yemeni people's determination to continue supporting the Palestinian people".
The reports came just hours after the UN Secretary-General condemned the latest developments.
Multiple attacks
"Israel's airstrikes against Sanaa's international airport, ports in the Red Sea, and power plants in Yemen are particularly alarming", says a spokesperson for Guterres.
Israel carried out airstrikes against several targets in Yemen on Thursday. According to Huthi-controlled media, a total of six people died in the attacks.
Israel's military confirms the attacks, which they claim were targeted against Huthi movement targets.
WHO on site
WHO's chief Tedros Adhanom Ghebreyesus was at the airport in Sanaa when it was attacked.
"When we were about to board our flight from Sanaa about two hours ago, the airport was bombed. One of the crew members on our plane was injured", says Tedros Adhanom Ghebreyesus in a statement according to BBC.
UN Secretary-General António Guterres expresses particular concern about the threat that the bombings of transportation infrastructure pose to humanitarian aid efforts in Yemen, where around 80 percent of the population is dependent on aid.
"The Secretary-General remains deeply concerned about the risk of further escalation in the region and reiterates his call on all parties involved to cease all military actions and exercise utmost restraint", the statement reads.
"He also warns that airstrikes on Red Sea ports and Sanaa airport pose serious risks to humanitarian operations at a time when millions of people are in need of life-saving aid".
