...Wickremesinghe, who returned to power in December after President Maithripala Sirisena fired him last year amid government infighting, said authorities had received warnings but “not enough attention had been paid” to them. The two leaders, from different parties, rule as part of a fractious coalition.
The premier’s comments amount to a "barbed reference" to Sirisena’s control of the police and military, which fall under the office of the president, according to Jehan Perera, executive director at National Peace Council of Sri Lanka. He noted the Tamil Tigers were never able to mount such a coordinated attack in the capital, Colombo.
“The prime minister is making a barbed reference to the president, and what he’s been up to, because his people -- the police and military -- have not been following up on leads,” Perera said. “The fact that this group was able to come in and do something in such a large scale way means that there must have been a breakdown of intelligence networks.”
