Israel is to accelerate the building of a huge barrier along its boundary with Gaza aimed at preventing militants from tunnelling under the border.
The 64km (40-mile) long construction will reach a depth of 40m (131ft) below and 6m above ground, at a cost of 3bn shekels ($833m).
An Israeli army commander said the barrier should be completed in 2019.
Israel has sought to neutralise the threat of cross-border tunnels since its war with militants in Gaza in 2014.
