Iraqi Prime Minister Mustafa al-Kadhimi has said he escaped unhurt after an attack on his home in the capital Baghdad.
Officials said his residence in the capital's Green Zone was targeted by a drone laden with explosives, in an alleged assassination attempt.
Earlier media reports said Mr al-Kadhimi had been taken to hospital.
In a tweet, he called for “calm and restraint from everyone, for the sake of Iraq”.
Officials said at least six people from the prime minister's security detail were injured.
No-one has claimed responsibility for the attack, in an area of the city housing many government buildings and foreign embassies.
The US has condemned the incident and offered its assistance with the investigation.
“This apparent act of terrorism, which we strongly condemn, was directed at the heart of the Iraqi state,” US state department spokesman Ned Price said in a statement.
Mr al-Kadhimi, a former intelligence chief, was sworn into office in May last year.
In recent weeks, supporters of Iran-aligned political groups have staged demonstrations near the Green Zone.
They have been protesting against the results of last month's general elections, which they said had voting irregularities.
More than 100 people were injured during violent clashes with security forces this week.(BBC)
