Trump returns from Florida amid Iran tension

US President Donald Trump returned to the White House from Florida on Sunday as the country's military presence in the Middle East was thrown into jeopardy.

Iraq's parliament on Sunday voted to expel US troops from their country, while the leader of Lebanon’s Hezbollah group said the US military across the region “will pay the price” for killing a top Iranian general.

Hassan Nasrallah said that US bases, warships and soldiers in the Middle East were all fair targets after the US drone strike that killed General Qassem Soleimani, the architect of many of Iran's regional military campaigns in recent years.

The two developments were new signs of the backlash from Friday's killing of Soleimani and a number of top Iraqi officials at Baghdad airport and further heightened tensions in a region already on high alert and bracing for an Iranian retaliation.
