An explosion was heard in Yemen's southern city of Aden on Wednesday, with smoke rising near the airport as fighting intensifies between government forces and the Iran-backed Houthi group, according to a police official and an Agence France-Presse (AFP) journalist.
The police official, speaking on condition of anonymity for security reasons, said the explosion was "caused by a Houthi missile."
The Houthis subsequently claimed responsibility for an attack on a Saudi-run military camp near Aden airport, saying they had targeted the facility with a ballistic missile.
"Our armed forces were able to target the Saudi enemy's operations room in the Badr camp in Aden with a ballistic missile," Houthi military spokesman Yahya Saree said in a statement.
A day earlier, the Houthis launched a deadly missile attack on the presidential palace in Aden, hitting command centres located inside the Al-Maashiq presidential compound, which is used by government forces and the Saudi-led coalition.
Yemeni government forces launched the "Dawn of Yemen" offensive earlier this month in an effort to recapture Houthi-held territory, including the capital, Sanaa.
Yemen has been engulfed in conflict since the Houthis seized Sanaa and several provinces in 2014, prompting a Saudi-led coalition to intervene the following year in support of the internationally recognized government.
The latest round of fighting erupted in July, bringing an end to a truce reached in 2022.
The Houthis have also targeted energy and aviation facilities in Saudi Arabia.
