NAIROBI, Kenya — Two people were killed and 62 wounded when two homemade bombs exploded on buses along one of the busiest highways in the Kenyan capital, Nairobi, authorities said Sunday, as this East African nation struggles to stop a series of terrorist attacks.
Of the 62 wounded, 20 were in critical condition, according to the National Disaster Operations Center.
Sunday's blasts were on two buses packed with commuters along Thika Highway, said Moses Ombati, the deputy police chief in Nairobi. Eliud Lagat, the deputy head of the bomb disposal unit said the blasts were caused by improvised explosive devices.
The explosions come a day after two blasts at the Kenyan coast killed four people. Police said a grenade thrown at a bus stop in the coastal town of Mombasa killed the four. The second blast at a public beach did not cause any fatalities, police said.
Kenya has been hit by a wave of gun and explosives attacks since it sent troops to neighboring Somalia to fight the Islamic extremist rebels, al-Shabab, in 2011. The Al-Qaida-linked militants have vowed to carry out terrorist attacks in Kenya to avenge the presence of Kenyan troops in Somalia.
Terror warnings have been a constant in Kenya in recent months, particularly after the attack on Westgate Mall killed at least 67 people in September. Al-Shabab claimed responsibility for that attack.
Last month, a car bomb exploded outside a police station in Nairobi, killing two officers and two men of Somali origin inside the vehicle. Police had impounded the car for driving on the wrong side of the road. Three ethnic Somalis have been arrested for the blast, and are expected to be charged in court this week.
Since last month, Kenya has been conducting a security operation in response to the terror attacks. Thousands of people, mainly ethnic Somalis, have been arrested in the security sweep which has been heavily criticized by human rights groups who say officials have carried out abuses. Police say the operation is aimed at weeding out terrorists and illegal aliens from war-torn neighboring countries, who are blamed for smuggling small arms and other weapons into Kenya through porous borders.
Rights organizations accuse the police of profiling Somalis, detaining suspects without trial, denying them representation, extortion, circumventing the courts to deport Somalis back home and holding the suspects in inhumane conditions.
