The White House Sunday "strongly" condemned the attacks on two Kenyan churches that claimed at least 17 lives and said the United States "stands with the Kenyan people at this difficult time", dpa reported.
In a statement from the press secretary, the White House also noted that the attacks in Garissa in north-eastern Kenya early Sunday followed closely after the killing Friday of an aid worker and kidnapping of others in nearby Dadaab refugee camp, and an attack last weekend on a nightclub in seaside Mombasa.
"The perpetrators of these attacks have shown no respect for human life and dignity, and must be brought to justice for these heinous acts," the White House said, referring to all the incidents.
The masked gunmen simultaneously attacked the two churches during prayer services, opening fire and hurling grenades. Two police officers on duty were also killed. At least 10 people were in a critical condition at regional hospitals following the attacks, according to the Red Cross.
The Supreme Council of Kenya Muslims immediately condemned the attack and sent condolences to the victims' families.The White House said that "peace and stability" were essential for Kenya's transition.
"We support those who recognize Kenya's ethnic and religious diversity as one of the country's greatest strengths," the White House said.
