Israel strikes Gaza as rocket sirens sound in Tel Aviv

Israel’s air force has hit Islamic Jihad targets in Gaza for a second day and Palestinian militants in the enclave have begun launching rockets across the border, setting off sirens and sending residents to shelter as far away as Tel Aviv.

The military said it was trying to hit rocket sites pre-emptively as blasts rocked different points including what witnesses described as a training camp in the northern part of the Gaza Strip and an open area in the south.

At least one man was killed and one wounded, medical officials said.

Their identities were not immediately clear.

Minutes after the strikes, sirens sounded in Israel – initially among border communities but soon also in and around the commercial capital Tel Aviv, 60km north of Gaza.

There was no immediate word of casualties in Israel, although local media reported a home was hit in the town of Sderot.

In Gaza, multiple contrails could be seen ascending as rockets were launched.

Mid-air explosions signalled interceptions by Israel’s Iron Dome aerial defence system.

On Tuesday, Israel launched a series of strikes it said were aimed at senior leaders of Islamic Jihad responsible for planning attacks against Israel.

At least 10 civilians were killed in the strikes as well as three senior commanders.
