At least 29 people were killed and 47 others injured late Thursday in multiple attacks that targeted military and security sites in Egypt's Sinai Peninsula, according to sources.

Three simultaneous bombings targeted military and security sites in the city of Aish which Egyptian state TV said had left 20 people killed and 36 others wounded.

But a medical source told The Anadolu Agency, on condition of anonymity, that the blasts had left 29 people killed and 45 wounded.

No official death toll has been given yet.

The state television said later that one officer and one soldier were injured in a separate attack on a checkpoint in Sheikh Zuweid in North Sinai.

ISIL's Egypt wing claimed responsibility for a series of attacks. A series of tweets from the Sinai Province's Twitter account claimed responsibility for each of the four attacks that took place in North Sinai and Suez provinces within hours of one another on Thursday night.
