Separatist rebels have lobbed a bomb into the official residence of the chief minister of India's north-eastern state of Manipur, officials say.
Okram Ibobi Singh and his family were unhurt. The bomb exploded inside the compound of Mr Singh's bungalow.
This is the second attack on Mr Singh's residence in the past year.
The separatist Peoples Revolutionary Party of Kangleipak (Prepak) claimed responsibility for the attack, saying this was "a warning " to Mr Singh.
Kangleipak is the ancient name of Manipur.
"We want to tell him that he will be punished for his misdeeds unless he mends his way," a Prepak spokesman told journalists in Manipur after Monday's attack.
Security was beefed up around the chief minister's bungalow at Babupara area in the heart of the state's capital Imphal after the attack.
Manipur is home to a dozen rebel groups - some fighting for the state's independence, others fighting for autonomous tribal homelands.
