Letters | After pager explosions in Lebanon, what next?
Readers discuss developments in the Middle East, and a new payment technology

In the future, couldn’t mobile phones, laptops or cameras be used to trigger explosions too? Airlines, railways and bus companies might be reluctant to permit the carrying or use of these devices on public transport. It seems that no one is safe anywhere.
The United States, Russia or China should be doing more to resolve the conflict between Israel on one side and Hamas and Hezbollah on the other. However, the US is preoccupied with the presidential elections to be held in November. Russia is embroiled in an attritive and protracted battle with Ukraine.
So, perhaps countries like China, India, the United Arab Emirates and Egypt should take the initiative to patch up the differences between Israel and its neighbours. If the world does not act now to ensure peace in the Middle East, we could be hurtling towards a major escalation and a world war, triggered by a thoughtless mistake.
