At least 13 people were killed in attacks in Kenya over the weekend, the Kenyan Red Cross said Sunday.

Gunfire erupted in Hindi near the popular tourist coast of Lamu on Saturday night, leaving four dead and two hospitalized, the group said after its preliminary assessment.

Hindi is near Mpeketoni, where attackers killed 65 people last month.

A second attack at a police station in Gamba caused nine fatalities, with one other person hospitalized and another reported missing.

Kenya’s tourism industry has taken a hit because of the attacks in the coast region. In May, tour companies evacuated hundreds of vacationers from Kenya after various nations issued travel alerts that warned of a “high threat” of terrorist attacks.

Al-Shabaab, a Somali-based militant group, has claimed responsibility for most attacks. It’s unclear whether the group was behind the weekend attacks.

The Kenyan military crossed into Somalia in 2011 to battle Al-Shabaab, which it blamed for kidnapping tourists in the coastal region. In retaliation, the terrorist group has launched a spate of attacks, including targeting bustling bus stations with grenades.

Last year, militants stormed the Westgate Mall in Nairobi and held shoppers under siege for days. At least 67 people were killed.
