An Iraqi security source says an airbase hosting US forces in the country has come under a rocket attack. The source said the rocket hit the Ain al-Asad base in the western province of Anbar. US bases in Iraq have come under increasing rocket and drone attacks amid rising tensions over the continued American military presence in the Arab country. Anti-US sentiments escalated following the US assassination of top Iranian General Qassem Soleimani and Iraqi commander Abu Mahdi al-Mohandis in January 2020.
