At least seven people were killed and three others injured in a suicide bombing at a mosque in Yemen's capital Sanaa on Tuesday, the Saba news agency reported.
A suicide bomber blow himself up at the Al-Nour Mosque within the district of Al-Nahdha during the Maghrib prayer and an investigation has been launched, it quoted a security source as saying.
It was the latest in a spate of deadly suicide bombings in Sanaa during the past three months.
Most of the bombings were at mosques attended by Houthi loyalists and claimed by ISIL.
Early Tuesday, car bombs targeted the hotel where the transition government is staying and residences of troops from the Saudi-led coalition guarding it in the southern port city of Aden.
Officials said the attacks were car bombs not rockets as reported by an official source early today.
No one of the government members were hurt and around 15 of the Arab troops were killed, the officials said.
The government returned into Aden last month after a six-months exile in Saudi Arabia.
It held a meeting hours ago and confirmed it will neither leave Aden nor will abandon its efforts to assume its duties topped by restoring security, they added.
And in response from its side, the Arab coalition, which has been bombing the Houthi militants since March, escalated airstrikes in several cities including Sanaa and Taiz.
