One Japanese national was killed and four others injured in terrorist attacks in Sri Lanka on Easter Sunday, Chief Cabinet Secretary Yoshihide Suga said Monday. The attacks left at least 290 dead and more than 500 injured.

Prime Minister Shinzo Abe told reporters that Tokyo "never tolerates" such violence, and is "determined to combat terrorism" by cooperating with the Sri Lankan government and internationally.

The dead Japanese national was a woman identified as Kaori Takahashi, a local resident whose age was not immediately known, according to a Kyodo News report quoting unnamed government sources. One of the four injured was reportedly a worker at the Japanese Embassy in Colombo, and another was Kazukiyo Yajima of telecom carrier KDDI Corp., according to Kyodo News.
